That was a repair near and dear to my heart being a fellow guitarist. Sounds like you know your way around a guitar too Buddy. You never cease to amaze me. Keep up the great work. Thanks for the fun and thanks for looking out for a fellow musician.
Buddy, I really love your videos. Had to watch the complete series on the '65 Black Face Deluxe Reverb Fender. That amp looked almost brand new by the time you finished with it. Cheers, mate. A '69 Band Master, that's the year I graduated from HS. You did a great job on that Band Master. Sounds great!
That's what I used as a working amp for years. Good heavy duty rig. Haven't had the amp for years, but still have the 65 guitar.
They are some tough amps Buddy.
I am glad you were working on this amp when I heard the motorboating I would have been wasting time looking for a bad filter cap. Thats what old tv repairmen do.
Thanks. Some times these sounds can throw you a curve. Thanks for watching.
Yep, that's exactly what I was thinking it was! Old TV repairman too.
Nice job Buddy. Always a good thing when old classic equipment gets resurrected and starts it's new life. Thanks for sharing it with us. 73 DE K7RMJ Frank
Appreciate it Frank. This was a fun repair. Thanks for watching.
Saw your channel, thought I would sub. Great videos repairing tube amps and assorted projects. Having 12 tube amps keeps me busy and with channels such as yours gives me a broader sense of what goes on these babies looking forward for more thanks Buddy.Kind of like Uncle Doug s channel. Hahaha. 🎸📻📺
Thanks for the sub! And the very kind comment. Love Uncle Doug's channel, but I am not worthy to be compared to him :-)
Thank you for helping to open my old eyes to electronics.I am learning a lot from your videos.Thanks so much for your time.
Another nice repair and someone is going to be happy to have this old classic back playing again. Get well soon, Buddy. Have a great Fourth!
Mel
Hi Mel. Thank you for the kind words. hope you have a great fourth also. Starting my vacation tomorrow.
Great video. I’m restoring 2 bandmasters now a 1964 and a 1967. Great channel I subbed. Keep up the great work!
Thanks and welcome to the channel
Nice one Buddy. I always enjoy the amp repairs. I recommend 2 weeks on the beach in Jamaica for that cold. 73 Doug
Thanks Doug. Man that would be nice!
Nice fairly straight forward and simple repair. A lot of collectors would cringe looking at that amp but that's what a working man's amp is supposed to look like. Now onto that pile of 15 amateur rigs that need fixing. ;-)
Going to be a busy two weeks coming.
You really know what your doing Bud. Thank you for another great video Buddy !!!....Angelo.
Thank you for watching my friend
Nice quick fix to get your friend up and running until the other amp is fixed. Love that term "Death Capacitor" - sounds like something out of Star Wars. Good strumming as well - can we look forward to a "The Radio Shop Album" of tunes? ;-) 73 - Dino KL0S
Thanks Dino. It was a fun repair. I am sure the Death Capacitor could take on the Death Star lol. :The Radio Shop" album of tunes eh? You mean classics like "Smoke on my receiver" " Hunk of hunk of burning circuit boards" And of course everyone's favorite "The night the lights went out in my TS-940"
@@TheRadioShop lolz...I would love to see the artwork for the album!
Hey Buddy,
I was waiting for you to break out a tune like Smoke On The Water!!!! Great repair!
LOL, Thanks Scott.
Buddy, those guitar chords sounded good. Especially that tremolo bar action. How about playing a few old Ventures tunes for us :)
Thanks very much Todd. Trust me when I say I am no guitar player. Just learning a few chords here and there.,
well-crafted repair video! keep them coming! 73 Tom, KY4TD
+The Radio Shop The DE-5000 LCR meter is a great meter. I have one, and I use it all the time. But, you almost have to add the kelvin leads to the plug-in connector box with the very short leads. They are terrible to work with as they come to you. But, are quite easy to mod. My kelvin leads came direct from China for about $8, including shipping. I removed the BNC connectors and soldered them in place of the original leads. It is very quick and easy to do, and passes the self-calibration routine. About the DE-5000s auto power down function. If you power it with a 9V battery, it will go OFF about every 5 minutes of use. But, if you power it with a wall-wart it won't do that. This is important because it has to be re-calibrated every time it is powered down. Also, if you look at Mr. Carlsons Lab CZcams channel he has a video with some recommendations for older analogue capacitor/LCR meters; some of which will do leakage tests. The DE-5000 has no function that will test capacitor leakage. So, I test leakage with a high voltage DC power supply and I measure the leakage current with my Fluke meter. Hey, it works and I don't have to devote more bench space to another piece of equipment.
Thanks again Ken. I am still looking and this may be the one I end up with. Appreciate the information.
Hope u feel better soon. Nice job on the old classic.
Thank you Rico.
Nice one buddy good repair big thumbs up
Thanks allan
Hey Buddy I can thoroughly recommend the de-5000 LCR meter I've tried a few but the 5000 is the best as you can change the frequency
You test at to match the manufacturers specs. I've found them very accurate and you basically need the meter the little test box with leads
which you modify with kelvin leads. I got mine with all attachments for $80 AUD off eBay brand new in the box in my state in OZ.
It has its own calibration built in. Check it out over there Buddy.
It's also on Amazon for $97.00.
Yeah the DE-5000 is very nice and also affordable, I have one I've been using for about a year. It's a very popular LCR meter now.
Thanks Peter, I will look that one up and give it a shot. Sounds like what I need.
Yep! Have one on the way from Japan as I type.
Tom Diamantes, Not able to reply to your comment, But thank you.
surprised to see you tested and didn't replace the bleeder resistors, I'd be scared of a return leaving them old things.
They got changed in the end. They tested ok but I decided to replace them before it left.
I have the same LCR meter as the one that you were using, they aren't bad for the money. Mine is pretty accurate. They have cases for some of these cheaper LCR meters now.
I have 6 or 7 of them in different flavors. I will say they do a pretty good job.
Some better capacitor ESR meters are capable of testing in-circuit, these cheaper ones require removal of the cap.
Hi, I have a question if you could help me out.
I have bought the bandmaster head and I wonder if it would be ok to run it through a 16 ohm speaker. I think the amp is supposed to run at 4 ohm .
great video! :)
Thank you dennis.
Keep it up!
Thanks
Can't go wrong with a tube amp!!! 👍
You got that right!
When I had my service center, I did warranty work for Ampeg. When Loud Technologies bought our St Louis Music, they sent out letters to all the service centers canceling all our parts accounts. The said they would still sell us parts, but a retail. I called them and told them in a not so polite way what they could do with their equipment and never did anymore warranty work. I told them to send it back to China. On another note it was fun dealing with guitar players. I serviced one amp head and had it all completely to factory spec, but the player said it didn't sound right. I had him bring his cabinet and guitar and while he played I changed capacitor values until he said "That's it, that's the sound". I promptly soldered in the appropriate incorrect capacitor and another satisfied customer.
Hi Bill, Thanks for sharing. I really do not like Ampeg at all. Terrible service from them. I know what you mean about the sound. You have to sit there and tack in several caps before you hear the right note. Takes a while also. After doing so many you can basically select a tested cap and be spot on. Years of doing it though. Thanks again.
Hey bud, I recently required this exact amplifier! It sounds great and you did very clean work. I can’t seem to get the vibrato to work. I tried a footswitch and a shorted RCA plug with no luck. I can hear the vibrato very slightly through the speaker and the speed is working but there is no vibrato sound. Any suggestions? Thank you!
I would start by looking at the coupling caps around the vibrato circuit. Also see you you can see the glow from the neon in the optocoupler glowing. Could even be the tube.
@@TheRadioShop , will do, thank you Sir!
"Must be low on oil..." :)
lol
nice job. i was hoping for some guitar play,
Thanks, Just wish I could play.
The RADIO SHOP, if you remove the CHOKE from the power supply , what would this do to the AC ripple voltage? would this add harmonics to the amplifier circuit?
I didnt see but did you put a fuse n the AC line?
Yes there is a fuse in the unit. Factory installed
I find it interesting on how collectors will get so passionate about leaving the vintage parts in place. To me if a device will not function then it is just artwork so you might as well collect a photograph. If you cannot use it why bother. Would a vintage car collector let the car just sit there because only modern spark plugs are available? Good quick work Buddy.
Well said Albert and thanks.
Collectors are funny people. I bought an old early 70s mopar, and it had the original factory spare tire in it. It still had the little nubbies on it from new and everything. Zero dry rot.
I put it on ebay, and I got so much money I was able to put four new tires plus a spare on the car. Talk about insane!
N95 mask for the concrete dust brother...just lookin out
new term "cookpacitors" because they're always burning out :)
LOL, I like that!
:)
Always good to see your smiling face.
+The Radio Shop Hi Buddy. **I'm sorry for bringing up such a subject here. But, I have the same sinus issues you do and I know how bad it can make you feel. So, I hope this helps you to feel better.** Here is something that'll help you to feel better the next time your sinuses are bothering you. All of my family members have allergies and are sensitive to environmental conditions, like you. So, especially when we're doing activities that require us to endure dust, my wife and daughter will use those face masks, but i can't stand them. So, as soon as we're done, we'll use a solution consisting of 1/2 quart of distilled water, with 1/4 teaspoon of baking soda, & 1/2 teaspoon of NON-iodized table salt. Heat a small amount of the distilled water in your microwave. When it is very hot, add the Baking soda & salt to it. Allow the gases to escape for a couple moments. Then, cover it and shake/stir it to dissolve the powders. Stir in the rest of the 1/2 quart of distilled water and continue to stir until you see all the powder has been dissolved. Before using the solution, test the temperature of it. You may have to wait a little while for it to cool. Next, you will use the solution to flush your nasal sinuses. Using a baby nasal aspirator/bulb syringe, fill the aspirator bulb completely with the solution. Then, lean your head back, close your nasal airway by lifting the back of your tongue upward. And, fill your sinuses with the solution; you'll feel and hear the solution bubble into the chambers of your sinuses. If you have infected sinuses, swelling may prevent you filling as much as you might normally do. But, do it anyway, it will help to heal the infection. And, if you have a cold it will lessen the time you have the cold. Do it several times to clear your sinuses as much as possible. Caution, while doing this, don't relax your tongue or the solution will run straight down your throat! Leave the solution there as long as you can. I've done this many times and have learned how to breathe while doing this. When you're ready, lean forward and expel the contents into your bathroom sink. Do this a couple more times. You won't believe what comes out. And, when done, you won't believe how much better you'll feel. We, in my family all do this regularly.
Thanks Ken for sharing that home remedy. I do not like taking meds at all. Much appreciated.
That Concrete dust is no joke, Please wear a mask! Concrete dust with moisture in your lungs is a bad mix, and no way to remove it.
HAHA Low on oil....
LOL< Glad to see someone got it.
I hope you checked the rod and main bearings. Sounds more like a rod.
