My dad passed away last September and I have been meaning to write this for a while.My dad got great enjoyment watching and learning from you and at the age of 80 decided to built a Valve amp which worked !! better sound quality than all the digital stuff he had purchased over the years.Just want to say thank you for inspiring people to have a go.keep up your great work all the best from across the pond.
thanks again terry
Thanks for sharing this very nice story with us. It's great to hear that our videos are helpful and appreciated :)
Uncle’s Doug video series legacy will outlive all of us and inspire millions-mark my words
We hope you're right, Fuga. Thanks !!
It's beaming out into Galaxies Far Far Away.... 🇨🇦🤓✌️
I hope we get some interstellar royalties :)@@garymallard4699
Thanks again Uncle Doug. Another masterpiece.
Id like to give a tip for collecting and isolating drill chips. By placing a collapsible rubber cone or a wax cup which is flanged that can be taped, over the drill coming through. In addition , a piece of duct tape on drill exit side will capture most hot chips. Duct tape around the drill side with the sticky side creating a crinkly sleeve to drill into. Cheap wide masking tape is easier to use and cleans up quickly.
Thanks for all the useful tips, Bob.
Uncle Doug
You are a blessing and a Godsend
I am lucky to have come across your presentations as I attempt my first amplifier repairs/modifications
Please please keep it up
Thanks so much, Ed. We're here for you :)
I'm sure you will regret that because of all the stupid newbie questions I'm gonna be asking now...
My current project is a silvertone 1482
Thanks for the reply
I trust that you will attempt to answer all your own questions and do adequate research before relying upon outside help, Ed. Good luck with your project.@@edhelmstetter2741
@@UncleDoug Here's one for you is it normal for that 1482 single 12 to light up the current limiter lamp a little bit if so it makes it very hard to get correct voltage readings. If not then there's that problem...Conundrum for sure
As it is the amp works but no tremelo. Tremelo worked before I replaced caps and resistors. Finding the issue should keep me busy for a while
Thanks for the help
It depends on the wattage of the bulb, Ed. A 100W bulb would definitely illuminate, while a 250W might not. The brighter the glow, the greater the reduction of circuit voltage and current.@@edhelmstetter2741
There are no mistakes unless it’s in the final product! That’s just part of the creative process. Excellent work as always!
Thanks, Ben. You're right.....corrected mistakes during construction are simply part of the evolutionary process :)
I am reminded of Jackie Gleason's reaction to the sup of coffee he was brought at the top of his show - wooooow! (sp)
Thanks, Andrew. I remember it well ;)@@andrewgillis8572
Beautiful amp. It will become legendary as one of the highest quality custom one-offs in history. This vid series will be used to establish the value of this amp in a few hundred years!
Tell us more about the guitar. Esquires are single pickup guitars, aren't they? There's a 1963 all-original for sale right now for 34 thousand dollars...
Awesome video series, Uncle Doug.
Thanks so much for your very kind words and flattering prophecy, JZ :) All Esquires were routed for two pickups, with only one installed and the other hidden beneath the pickguard. This makes it possible to add a second pickup without altering the guitar in any way, other than replacing the original pickguard with a double-cut (i.e. Tele) one.
@@UncleDoug Thanks for that. It would be interesting if you put a price on that one-off, hand built, custom designed masterpiece of an amp. It might realistically be priceless.
Thanks so much JZ. Even at minimum wage it would cost over $2K.@@AgentJayZ
@@UncleDoug Long after we are gone, and thanks to these videos being immortal, people will be bidding what we would think are unimaginable fortunes for your hand made works of art. Some billionaire in the future will chase after, and finally assemble a collection of all your scratch built jewels, and for comparison will also display the hand-built Grable you were so impressed with. I hope they all get played, and properly cared for until electricity is no longer used, or even available...
Wow, I'd be hard pushed to let that beautiful amp go, after putting so much heart and soul into it. Great job I enjoyed every minute if the build. Thank you Doug.
Thanks, Tim. I don't mind sharing my creations with people who truly appreciate them. It's a win for both of us :)
Doug, your CZcams channel is now officially my favorite. You're the Bob Ross, Jaques Pepin and Bill Murray of amp geeks. This series, like all your videos, was utterly captivating, and the results sound fantastic. With this design is the overdrive we're hearing from the preamp or power tubes? In some future video, would you please consider discussing the difference between preamp and power tube overdrive and how to get them? If you've already covered this, would you please direct me to the video(s)? Thanks!
Thanks so much for your very kind words, Dave. The only overdrive I really noticed was with the low gain input and relatively high volume setting. Since the circuit has no Master Volume control the distortion is probably from the output tubes. I am not really an expert in distortion, since my audio demo's are generally fairly clean. There are all sorts of great sources on the subject on the Internet, however.
"Do one thing, and do it well." You, sir, are the epitome of this philosophy. Although that's a little presumptuous of me since I don't know what else you do, LOL.
He builds some pretty cool hot rods too
Thanks, fellows. We do our best ;)
Dear Doug a simple way to create more room on the 9 pin sockets is to half way fold back each pin, e voila' more room is created, which also avoids potential short circuits. It works for me.
It worked for me too, Vincenzo. Thanks for your input.
Point-to-point wiring can be an art form or a mess of spaghetti.
You definitely should be proud of your work, leave a "made by" note on the chassis.
Thanks, Mack. I did.....on the cabinet wall.
Thankyou Uncle Doug for all your do. I have binged on your videos this Christmas break. I have to keep studying for my P.Eng. CPD. (Continued Professional Development). So I watch your and others videos on tube theory. I also read books. I might even build one of the kits for fun. I did built an Audio Dummy load with meter over the break. Designing an amp would be fun using some different tubes from the common old favorites. Going through the load line and choosing a bias point for just the right amount of distortion or lack thereof. I wish I could do woodworking like you do. My attempts always end up dirty.
Greetings, Ak. We're glad the videos have been interesting and helpful. Best of luck if you do choose to design and build and amp circuit. Let us know how it turns out :)
New subscriber. I'm thoroughly loving your content (and am currently binge watching most of it). I haven't played with tubes since the prior millennium, but you've given me the bug. Gotta say my favorite part of this one was the cat hairs on your computer monitor (mine now has finger smudges from trying to wipe them away!).
Greetings, IK. Once you get to know us better, the cat hairs will not be a surprise :)
uncle doug, good show because not a lot of youtubers build there own amps from scratch thank you for your time doing this 👈👺👀👀👍
Thanks, Ralph. Glad you lied it :)
Earlier today I was deciding what to watch on my day off work. It occured to me that I haven't checked in on what Uncle Doug has been up to for a while. I'm so glad I did. I've got a bear of an amp repair I need to get started thinking about (original first year model Peavey 5150 Block letter head). Between you and others on CZcams, real tube amps aren't magic and voodoo anymore. Time to start hunting down a bunch of caps and some discontinued potentiometers.
Thanks for watching, Chad. Best of luck with your repair project.
I have no idea about most of these videos but I really enjoy watching them. Its always good watching a master work.
Thanks, B. We're glad to hear it :)
That episode has a lot of info to take in, Especially the new grounding and smoothing circuit. I m going to have to watch it again and make notes. Thoroughly enjoyed this build Doug. What a peachy amp, along with the Esquire tones. That was a treat. Customer must be thrilled.
Thanks for appreciating all our work, Alex, and for your kind words. He was :)
Start to finish - Specf'ingtacular!! All of the workmanship is absolutely 2nd to none - a pure museum piece ! UD - thank you so much for bringing us along for such a fantastically great and fully accomplished project. The person receiving your work of perfection is one VERY lucky person.
Wow...thanks so much, Skip :)
Uncle Doug is a Genius
Aw, shucks, Sid. You are too kind ;)
I’m temporarily looking after a feral rescue kitty, Mimi
I never thought I’d warm up to a cat in my house since I have 4 parrots, but she’s a cute, polite girl.
Once you get hooked on rescuing kitties, you'll wonder how you ever lived without them ;)
An exemplar of instructional videos.
Thanks, Ross :)
I had reservations of the power trans being so close to the speaker magnet. I was wrong. Nicely done.
You're not necessarily wrong, Jerry. It's just that I have never had any issues due to their close proximity.
Man, that esquire was sweet. Amp sounds good too
Thanks, Joe :)
This series was really interesting - thanks Uncle Doug!
Glad you enjoyed it, AC :)
I must say this build turned out really nice. That chassis is a real masterpiece both topside and under deck. A real solid performer as well. Looks great and colorful with all new components & tubes. Be proud of this one, UD!
Thanks so much, Daniel. I, and hopefully the owner, agree with your comments :)
One of a kind, fully documented masterbuilt, amp by Uncle Doug. I would proudly own this amp, if it were mine!
Thanks for the nice comments, TFE :)
Great program Uncle Doug! I like the problem solving. Thanks for recording your thoughts throughout the video. I have to admit, my pucker factor was pretty high during the final shaping of the chassis... No different than finding out your power steering pump doesn't clear your freshly powder coated hot rod frame and having to hack in a relief! Sounds great!!!!
Thanks so much, Greg. Excellent analogy......I'll bet you liked the air grinder being used on the tender little arc of sheet metal ;)
@@UncleDoug I was hoping you'd break out the plasma cutter. :D. In all seriousness, I was trying to solve the problem before I saw what you did... Too thick for hand snips, no clearance for pneumatic shears, air saw is out, plasma is too messy... I was left with roughing it out with the whizzer wheel, then cleaning up with a needle file or die grinder. A sanding drum on a drill press was another thought I had for the cleanup.
The solution initially puzzled me too, Greg, but fortunately it all turned out OK :)@@GregsGarage
Just wanted to wish you a blessed New Year on this Jan 1st 2024. Thank you for your devoted efforts to teach us all valuable information about electronics. Stay blessed my friend. ❤️✌️😎👍
Thanks so much, RF. Will do.....you too :)
Sweeet! Thanks Mr. Uncle, and Cats ; )
Glad you liked it, Lu :)
This build is sooooo clean. I so highly appreciate all the information given over the years. I´ve learned soo much already, just from your vids, reflecting in repairing amps myselves. Please keep up the good work. Love frome the Netherlands and happy holidays
Thanks so much, Eric. We're glad to hear that our videos have been helpful :)
Thank you Uncle Doug for another wonderful series, it takes me back to the very first amp I built witch was an Angela Super single ended version of a Princeton circuit that worked first try leaving nothing the fix but a pesky polarity switch that would blow the fuse if switched while on but would work if you switched it when off, I deleted it!
You're welcome, Jeff. Glad you enjoyed it :)
Pretty tight quarters inside the chassis. I'm not sure I would have been able to make all of the solder connections with my poor eyesight. Nice touch to show the cat's holiday greetings!. Now you can book a date at Miguel's to demo the amp.
Apparently the owner will be using it in a public venue later this month. I await the result :)
Happy Friday. Looks amazing and sounds fantastic! According to the internet, the next full moon will be Dec 26 at 10:33 pm. We should all howl in unison that night to salute this spectacular addition to the family of amplifiers! We loved the kitty cat pictures and drone footage!
Thanks so much, Wyo :) A very Merry Christmas to you all :)
@@UncleDoug Merry Christmas to you and yours too!
Another great video. I've been watching for years!
Thanks, Doug. Glad to hear it :)
An hour well spent for me this morning! Thanks, Uncle Doug!
Glad you enjoyed it, Ken :)
What a brilliant teacher Uncle Doug is, makes things a lot easier, than gobs and gobs of technical theory. Well done Uncle Doug and thanks so much for all your videos sharing your know how.
Wow.....Thanks so much, Polly. :)
Hmmmm.. Tremolo Strip.. that was my girl mercedes' signiture move at the Slippery Chalet. Ahhh memories... 😮 Greetings from yootoob land!
Better than the "reverse audio pot" move my girl had ;)
Thoroughly enjoyed this series. Very relaxing and informative way to spend some free-time. Music demonstration, with all it's beautiful jangly tone, inspired me to leave the Marshall high-gain stuff alone for a little while and see what that Deluxe Reverb in the back room might sound like with a telecaster again. Impressive build and excellent video production. Thank you Uncle Doug!
Thanks so much for your very nice comments, TK. We're glad the video was inspirational :)
Wow ! Great Build, Thank you
Glad you like it, Bob.
Coming at you.. from the tremolo capital of the world 😜
Just down the road from Reverb Junction ;)
Uncle Doug you are truely a genious and I greatly envy you I would have to live two more lifetimes to understand all that you show us out here in CZcams land . Thanks for such great videos and I must say most of my projects I always have to go back and redoo a few things and a few times at that. thanks for the drone footage of the boarder my how Elpasso and Huarez have grown . I was unaware though that Fender Esquire ever had a neck pickup maybe it was an option or my info is not correct
Wow, thanks so much, 20x20. The neck pickup was added in the factory-routed inlet present on Esquires.....just like Bruce Springsteen did.
I really dig the sound of the low gain input. The amp sounds killer. Super nice job building it.
Thanks, BH. I agree, the low gain input plus increased volume = a bit of "hair" :)
Great job! The amp turned out fantastic. My experience scratch building amps is much like yours. Dive in and Fix as you go. My results usually were not as good as yours but it is an excellent learning (and humbling) experience. Kudos!
Thanks, FBH. We're glad the videos are helpful :)
A toggle switch in one hand, a crucifix in the other - I like the way you think! Another beautiful instant classic. Thank you, UD!
Glad you enjoyed it, TP. A little religion never hurts ;)
Well done Uncle Doug. 🎸 👍
Thanks, Phil :)
Nice! That thing looks like an old military radio inside.
Thanks, Alan.......I guess ;)
Dear Uncle D, I am following your videos for about 1 ½ years now but didn't get around to commenting until now. So, firstly I joint the chorus of praising your work and your presentations for your clear, well-pronounced speech. I have to say though, sometimes I think your explanations go into too basic a level. I feel that people who need explanation of principles such as Ohm's Law should better keep their hands off these high-voltage circuits.
Oh, but I love the appreciation you show towards your felines! Accordingly, I much enjoyed the pictures of your crew, although I wish you would have put their names with the pictures.
Now, at last, to this current amp - congrats for your skills to make all features instantly working and for its sound! You crammed a lot of features into the fairly small chassis for that small housing, and the wiring must have been quite a nightmare in the later stages! Since you used high quality components, one would hope there will be no need arising for a repair - which I guess you would not like imagine of doing.
I got myself into said troubles with my second self-designed tube amplifier with a crazy circuit and very elaborate power supply. Now it developed a short in the power supply, and it drove me to the thought of ripping it all up and making a new, at least 50% larger chassis for it…
Looking forward to your further videos and wishing a lovely Christmas!
Greetings, Regal, and thanks for all your comments. As with all home-builds, hopefully, the circuit will never need to be repaired ;)
Thanks for a year of fun🎄🇺🇸✡️✝️
Thanks. Hopefully we'll have many more :)
You can get away with "winging it" because you've got a lifetime of stored experience to draw on. Great outcome!
Having a lot of experience with circuits like this does help quite a bit. My first attempts at scratch-building were less "adventuresome" ;)
As old Hank would say "You Win Again".
Thanks, Steve.....and so does the owner :)
Outstanding!
Thank you kindly!
Fantastic job Uncle Doug!
Thanks so much :)
Cripes Uncle Doug, what an amazing build!
...and such a super high quality video (as per your usual)
Thanx so much and Elvis sez "Hello" to your gang
(He actually said 'Hello' and, of all things 'meow'... He gets talkative in the kitchen)
Thanks, Jonny. Our kitties wish you and Elvis a very Merry Christmas.
I have a Hakko FX951 soldering iron and the handle is slim to reach in and solder in tight spaces.
It's so good, that there are many copies that are sub standard so if you try one, be sure it is a true hakko FX951. You will love it!
Thanks for the tip (no pun intended). I'll look for one and give it a try. Follow up: I checked and they cost around $300, Darryl, which inspires me to continue using my own iron. Thanks anyway.
Well DONE,UD! Nice sparkle and growl. THAT is vintage tone! Beautiful chassis work as well. The outline of the decals really blended into the background nicely. You just need a broomstick to go with your crucifix so you can take cover while switching amps on for the first time,lol! Really killer sounding and unique little combo! The chassis work…wow! The owner is gonna be ecstatic !
Thanks so much for your very positive comments, William. We sure hope so :)
My gosh uncle Doug! You really knocked it out of the pzrk with this build. That little beast gets the kind of sounds an tones i have been seeking for years to obtain at low volume. Also thank you so much for including the holiday wish segment from all the kitties. Merry CHRISTmas from my feral kits to you an yours. You have encouraged me to seriously dig out a dead amp i have that uses i believe a 12bn7 for its power tube an try to make a point to point circuit out of it as it somewhat got me those sounds at a tv set volume. Thanks again for this epic series.
Thanks so much, SC. Actually the volume of our audio demos is much higher than you might assume from the recordings......but the Suprinceton definitely did provide great tone at moderate volume, largely due to the NFB being switched off.
@@UncleDougI'm using a modern fender super champ, also running 2 6v6. I know 10 watts is supposed to be considered "low output" but to get a good tone you sure have to crank it until its pretty damn loud for home use! I must be gettin old!
We found that by using the low-gain input with the volume double that with the high-gain input, the resulting tone was quite nice. @@stratcat4450
A real Ear Gems presentation in 3 parts. Fastidiously built .... especially for a free-form scratch custom!
All my best to your family and felines for Christmas! ❤
Thanks so much, Willy. Likewise to you and yours.
Really nice, I love the point to point wiring.
Thanks, Michael.
Incredible build Uncle Doug! Your channel taught me how to build my own point-point JCM800 which has been serving me well for two years now. Happy holiday season!
Thanks Cam. That's great news. Likewise on the holiday good wishes.
BBeautiful build uncle Doug.
Thanks, Monty :)
Bravo, Doug!
Thanks, Chris.
Looks like a thermionic masterpiece.🤠
.........and hopefully sounds like one too :) Thanks, FH......I say, thanks.......he's a good kid but he just doesn't listen ;)
Nothing beats an Uncle Doug build (with mods) Love it. Some of the tech stuff eventually rubs off on the keen viewer
Thanks, Garry. We hope so :)
Ahhhhhhhh...perfection! The amp is majestic, and the high gain/CBC on tone was especially good to my ears. Something about that tone just commands attention, and won't take no for an answer!
Thanks for your very kind assessment, CJ.
As an electrical engineer with decades of low noise analog experience and a guitar gear geek who hopes to some day build an amp, I am thrilled to finally see a hand wired amp with single point grounding. Well done all around! That chassis looks like soldering had to be a challenge with so much wiring and components in such a tight space.
Thanks so much, Greg, especially from a viewer with your experience. Yes, waiting 'til the end to install the 6.3VAC wiring helped a bit, but burning nearby insulation was a constant concern.
Hi Doug, the way you explained the steps and then showed the resulting wiring path in concert with the wiring diagram was absolutely top class. I always had some difficulty understanding the way in which the tremolo components went together, not anymore. Similarly I finally know what the pot symbol means that has the arrow obliquely through it. I just always thought it was the old fashioned way of displaying that. I now know what it actually means. In addition showing which actual points on a pot are the wiper and each terminal in comparison with the schematic really helps. All in all a great job so thanks for your sterling efforts.
We're really glad to hear that the video was instructive, Allan. Happy Holidays !!
Nice work, as usual
Thanks, David :)
I have to say, your prowess and confidence on the guitar really shows through on this video. Great job! You build with the same mindset as I do.....I'll fix the problem if and when I come to it. And schematics are a great starting point. Creativity. Very cool. Excellent build, great sound!
Thanks so much for your perceptive input, Mr. K. I guess we're both believers in doing rather than planning ;)
Nice work as always. Thanks uncle Doug
Thanks, Daniel :)
Absolutely beautiful. Thanks for everything you do for us viewers on CZcams. You are a treasure Uncle Doug.
Thanks so much, Peter :)
Well done sir. Ollie and Jack have improved in leap's and bound's. Merry Christmas to you and yours.
Thanks so much, ES. They will appreciate your kind words :) Likewise on the holiday greetings :)
excellent work, Doug and education as well!
Thanks, MB :)
Well Done Doug, Merry Christmas from Wisconsin!
Thanks, KB. Back at you from West Texas :)
An epic and beautiful project.. ✔️✔️✔️👏🏻👏🏻👏🏻👏🏻
Thanks so much, Jennifer. High praise indeed from someone with your experience and technical acumen :)
Masterpiece theater 🫡
Thanks, TA :)
Well done UD and outstanding craftsmanship sir. I had no clue that the CBC switch would add that much gain and growl. Thank you for continuing to educate and to share you knowledge.
Thanks, JT. I was impressed by it also and may begin offering it as an added feature to amps being repaired.
You are a bright light in our digital world!
Actually I would prefer "tubular" world ;)
Uncle Doug, you were speaking of wiring the tight tube socket leads.
Years ago, after college; SUNY@Buffalo ( BS) and Berklee College of music ( BMUS),
I apprenticed with a vintage guitar repair friend. He told me to use “whiteout “ on the
lugs in close situations, when we didn’t want solder to migrate to others.
Of course,you remove the whiteout, when the lug is needed.
Maybe you know about this?
He was my mentor, before and after both schools for music and guitars.
I was pre med at UB, he was a Pro bass player and had gotten a full ride
to UB for electrical engineering. He took me to all of his Jazz and Rock gigs.
Somehow I lost my mind and decided that music was my calling.
Thanks to him, I learned what most never learn. I got to play vintage guitars,
that most have never and will never play. Every model Gibson 50’ 60’s pre CBS Fenders, etc.
Real Bursts, Firebirds, LP Specials and Jr.s , you name it.
Vintage Amps of all kinds. He even sold me my 1954 Fender Deluxe TV face amp for $ 75.00!
He sold me the best of the best of Vintage guitars for what he paid.
The only caveat, was that if I wanted to sell any, I had to sell it back to
him for the same price.
His name was Scott Freilich ( RIP My dear friend).
Sorry for my ruminations
Thanks for sharing these experiences with us, Jamie. I have seen the Whiteout trick on "Forged in Fire" but have never tried it. Perhaps now I will :)
Hope the whiteout helps👍🏻😊
Great sound for a small cabinet!
Thanks, Fred.
Need to print another Uncle Doug decal and put at the top of control panel. Sounds great!! Never expected anything less!! You're the best!!!
Thanks so much, DR :)
Ollie & Jack are Mick Ronson fans! Great sounds, beautiful build, Uncle.
Thanks so much, JT.
Magnificent Doug. A super effort, keep it up
Thanks, Ex. Will do :)
That little amp is a beast.
Sort of like a "sleeper" car that appears slow and innocent......but isn't.
Oh lord that drone music made me cry so good!
Glad to hear it, DN ;)
Great video! From your fans in New Mexico with the green enchilada casserole.
Thanks !! That's exactly what we had for Christmas dinner.....with Hatch green chilis :)
I don’t know about “No Satisfaction” but you certainly satisfied my lust to see this magnificent build completed. Nice sounding amp. Twangtastic.
Thanks so much, PtC :)
What a great build!
Thanks, Zach :)
Nice little “cult style” short subject video production of the local scenery. This amp demonstrates the luxury of space for boards to provide interconnects. Very nicely explained, and artfully executed. Sounds good too…
Thanks, Brian. Glad you enjoyed it :)
Such an absolute damn treat to see this! Thank you for bringing us along, Uncle Doug. Cheers to you and yours!
Thanks so much, S35. Glad you enjoyed it :)
Sounds great, Doug!
Thanks, Chris.
Nicely done!
Thanks, PK :)
@@UncleDoug I am wondering how you decide which wires need to be twisted in order to neutralise the electromagnetic field and noise they produce?
Easy, PK......it's the ones carrying AC to the filament heaters.@@PetraKann
Simply Awesome!
Thanks :)
Great amp! Great guitar! Yes very encouraging!
Glad to hear it, Victor :)
Excellent build...sounds amazing.
Wishing you and family Merry Christmas and Happy New Year!!!
Thanks so much, Doc. Likewise to you and yours.
In hindsight, what do you think of the design of the tremolo circuit? Do you like it as well as the versions with LDRs? I really don't understand how this version modulates the amplitude of the audio signal (but it obviously does!)
I personally prefer this much simpler, quieter tremolo circuit to the Photoresistor style, Pat, but this type works best only with relatively low-wattage amps.
What a wonderful trilogy Uncle Doug and band. I look forwards to every episode with relish and these last few have not disappointed at all. From my family to yours I hope you have a great Christmas and here's to more in 2024.
Thanks so much, BN. Merry Christmas to you all :)
Absolutely superb series. Having built a number of amps from scratch I can testify to the challenge and this is one of the best outcomes I have ever seen. Really enjoyed the interludes as well. Best wishes.
Wow....Thanks so much, CM. Glad you enjoyed it :)
Really love the P2P philosophy.
Thanks, HJ.
Beautiful wiring here Doug! I really enjoy your PTP builds. I find it to be a lost art!
Thanks so much, Kley :)
That is "Suprinceton" cool!
Glad you enjoyed it, Randy.
