Someday I’ll be able to sneak a vintage Bassman into the house without my wife noticing… For now, I’ll just have to watch Lyle restore my dream amp…
There’s some really good parts out there to build an amazing replica. Not a “clone”, a Replica.
Everything, including the tubes, lacquered tweed cabinet and speakers is under $1600.
I am very familiar with the 58 -60 Bassman and have built ~10 replicas. Right down to the voltages and off schematic changes Fender did in the late Tweed era. It’ll get you 99% there.
I do understand wanting an original amp though. I had one years ago and I foolishly sold it.
If you want a replica, I can point you in the right direction. If you’re anywhere near SoCal, I can build it.
Another great video! Thanks!
I have a 1961 G6G A Bassman. I traded my 1984 JCM lead Series Marshall Head for it. They are out there. Patience.
@@matthewf1979unfortunately, the missing percentage is in the speakers, and I’m afraid that it’s far over the 1% that you mentioned. Until we can replicate the paper formula that was used in the original Donal Kapi cones, we will never be able to replicate the original sound of these amps. You’re right though, we can replicate pretty much everything else. We’re agonizingly close, and certainly close enough for most people’s standards. To call a spade a spade, though, we are not able to get the original sound of those speakers
Witnessing the resurrection of a prized classic. I have always enjoy watching the process of restoral. Your "clean slate" modality is how a quality tech should approach this endeavor. I know the owner, as well as the subsequent owner, can watch it for themselves. I await the next spinetingling episode of this grail of amplifiers.
Learning has occurred! When you pointed out the grid stoppers, on the board, i thought to myself; 'should they be at the octal sockets?'
I thought I knew a lot about tube amps before I started watching Lyle. I'm humbled, but I've learned so much from him.
The idea that Lyle can take it apart, at the same time explaining what's what, and why and not burning himself; then in a future video, putting it all back together while explaining what he's doing....and being his own cameraman is ....amazing.
Indeed. An impressive and enviable depth of knowledge. This is going to be one highly desirable Bassman.
Anyone can take things apart. It's putting them back together again that counts! You got this.
" little giblets of solder...* excellent description!
Thanks Lyle,
Watching and enjoyimg very much!
Off topic a bit, but a couple of weeks ago I had commented that I had a '73 Fender Champ that was in good condition with original speaker with a cone that was basically dust. You recommended that I just put a new speaker in it. I just put in a Jensen P8R4 and it worked! Imagine that. A 50 year old Tube Amp I've been lugging around for 40 years, sitting in a closet or a storage unit turned on and works! Entirely original except for the new speaker (I guess original can be re-coned) I was amazed.
Great angles of the tube socket wire removal. Nice job.
I can smell that old solder fumes!
Love the attention to detail that you put into all the work that you do Mr. Lyle. It doesn’t matter if it’s a vintage piece of history or if it’s a new piece fresh from the factory your attention to detail doesn’t change. You sir are an inspiration to us all who are trying to learn how to maintain our own gear. May you live long and prosper.
I admire your patience.
I look forward to the next installment
It’s going to be a work of art!
I was always curious about a '58 bassman that was supposedly a prototype Gruhn guitars had at one time. It had an unplated chassis with two rows of knobs and 3 10inch speakers from what I remember.
always a great video....... Thx as always!
Hi Lyle, glad to see your hands have cleared up.
Mahalo Lyle! Good video.
I'm subscribed and hit all notifications but not recieving anything. Luckily I stumbled on this episode. I enjoy your work and knowledge and humor. Also the proud owner of a 61 bassman. Original circuit.
Thank you!
I hope that you are feeling better Sir.
2:13 extension tubes, or a "close up" lens (achromatic, a little more expensive than regular ones, but give good results) do the job well
That amp is as old as I am, and I know I'm not in anywhere near as good condition. I can't wait to see how it looks once rebuilt. Great work, as usual
Please show how you clean cloth insulated wires.
This is one of those amps that deserves some of the parts in my NOS stash.
Agree, with all of those new parts in there (esp those orange drops and tube sockets), whoever buys it is paying more for the transformers than anything else.
Thanx Teach...
Looks like an abandoned spaceship taken over by some weird alien lifeform.
I'm a big fan of grid stoppers. Grid stoppers everywhere! And you are 100% correct, they are best when located as close as possible to the grid.
Fender removed the grid stoppers on the 5F6A power tubes. That is part of the sound of the 5F6A and grid stoppers should NOT be put back on the power tubes.
@@bluesky6361 you can bet dollars to doughnuts, when Leo deleted the grid stoppers on the 5F6-A, it had nothing to do with an attempt to improve the sound. It was a change intended to save a few pennies on components he deemed non-essential. The fact is, any difference you would experience with grid stoppers is 100% beneficial. They limit grid current in the event the grid is driven positive which reduces blocking distortion. They also reduce parasitic oscillation and instability. If you're a fan of either of those maladies, by all means, don't use grid stoppers. As for me, I find them ugly and highly undesirable, so I'll continue to use grid stoppers in my amps. YMMV.
I shudder to think what vaping gunk is going to look like inside gigging amps ...
Outstanding work Lyle as always ,Did they use a Dielectric paste on the Old pots in this era? I heard a few years ago from another tech that some pots had a Dielectric paste in them and if you sprayed them to clean it can spray out the paste ,he actually took the pots apart and put new paste in but it may have been old audio equipment
Hope someone here purchases this amp.
Especially since the go ahead to make it right has been given to Lyle...!!!😉👍
They will forever be glad they did so.
Wish it could be moi...!!!😊😮
Looking forward to hearing when completed 👍👍
Anyone have a guess on price? I am guessing $6K - $7K?
So nice this amp is going to be "players grade" freshened before sale. A collector would want it 100% stock and humming/smoking I guess? ;)
No, a collector would want original iron, tolex, etc. 3-wire power cord, fresh electrolytics, and other items that make it less than 100% stock would be completely acceptable. Things like the selenium rectifier should still be in place, but not in the circuit.
Do you find a lot of tobacco resin in old amps like this? A guitar shop I follow said they had to air out an original jazzmaster for days because the insides were coated in so much tobacco smoke.
Night's amp is exactly where it needs to be right now!
I totally missed the live stream, thanks to Grainger. I was having a rare genuine nuclear meltdown at a WW Grainger. Those idiots put my will call order through to a Grainger 30 miles away, and told me to drive 30 miles to go clear across the city, to get my will call order. I had my mom and my brother in the car, and we all had hospital visitor badges on, so I kind let go with a "Go find my ******** stuff, because, I know it's 100% in stock here, and we are not driving any 30 miles!" What a nice treat to see a lovely Bassman that belongs plugged in and making some good music instead of sitting in a glass case between a cigar humidor, and reproduction suit of Roman armor.
Doesn't the 5F6A usually use tube rectification? Is the selenium rectifier a factory thing? And does the selenium rectifier eliminate sag like diode rectification?
Thanks, you ARE the man.
The selenium rectifier (as well as the silicon diode that replaced it) was used in the negative voltage bias ciircuit that feeds the grids of the output tubes. This amp is indeed tube rectified as far as the main B+ supply goes. The leftmost octal tube socket is for the rectifier tube.
@@jimsalman7257 Ah....thanks. If I would've paid better attention (or watched pt.1)....I should have known about the rectifier socket.
Yes, I see it on Robinettes page, a bias rectifier (using a generic diode symbol) tied to the bias caps and grid leak resistors off the 5881's, with the other side coming off a tap between the center tap and 325V plate supply voltage for the GZ34.
On Robinettes mods, it looks like he creates a 50V bias supply by tapping a bridge rectifier. I guess that's a pretty common method.
Thank you very much for your informed reply.
I'd love to have that old Bassman, but I need another 45 Watt, 4x10 Fender amp like I need another hole in my head.
Looking good, Billy Ray!
Out of curiosity, what do you use to clean the old wire insulation?
I used isopropyl but most of the wire will be replaced as the cotton insulation is semi-rotten. Insulation is much better when it actually insulates.
@@PsionicAudio IMHO, you honor the amp much more by this replacement. Restoring proper function and reliability is the most respectful thing you can do for it. 👍
What they said....
Hope you're all healed up.
Mo Money, Mo Money LOL
I probably can't afford it, but I want to know what he's selling it for.
"Retired from gigging"? Never happens! You just play smaller venues...like the living room and the upstairs bedroom. Believe me, selling that amp because you think you are "retiring from gigging"...well, I did forty years ago (from paying gigs) and still wish I had some of my vintage equipage. Jus' sayin' 'z'all...
I think a lot of pros see their equipment as tools to get their job done and aren't particularly sentimental about them. Personally, I AM sentimental and even though likely never gig again, I miss a lot of the amps I've sold!
