We have a small budget on an amp that requires quite a bit of work. Here I'll see what can be done on the cheap, or if the budget will need to be increased, or the job declined.
I screwed up when initially measuring the ripple on each node, as videos go. But I left it in anyway.
You can be assured there was ripple on the screen node exceeding 0.6vac.

What I tell people asking about original caps is that Leo Fender started out as a radio repairman. And the genius of his amp designs is that he made them easy to be serviced. *Because he expected them to be serviced.* He would view a 60 year old cap as a slap in the face to everything he was trying to do with his designs.

I am getting really sick of needing to go into an argument about it every time. I just decline those kinds of jobs these days. There are plenty of other local repairers who will entertain that philosophy.

I've had premature failures with CE can caps. I used another a few weeks ago, so fingers crossed on that, but I think I'm going to make a standard replacement board for Champs/Princetons so I don't have to use them in the future. A little FR4 board that will sit over the old cap and allow high quality radials.

Do your black face champs / vibrochamps over there have those 3 holes in the chassis like this one? Or was that an export only thing? They could potentially be used to mount a PCB / turret board without modifying the chassis.

Damnit. I guess I’ve just been very very lucky and haven’t had a CE multi-section fail yet…but now I’m more than a little concerned. What’s everyone’s thought about using a 30uf on the first node and 22uf at the other two? All 500VDC of course. Would solve the over-voltage at cold start and also add a bit of capacitance on the first stage to remove the small remaining ripple without exceeding max load of the 5Y3.

Totally in tune with your thoughts and experiences . Doing half a job is no good for the customer or our reputations . Yet still , once in a while a job can come back with another problem . A classic valve amp is like a classic car . It's going to need maintenance , and other things will still fail . It's naive for anyone to think otherwise . And those modern valve amp models that we don't want in our workshops are the car equivalent of high performance vehicles . They're going to need a lot more maintenance than a run-around , and it's going to cost the owner sooner or later .

New caps in an amp is a good thing.
@BradsGuitarGarage
@BradsGuitarGarage 2 года назад
Damn straight. Trying to preserve a sound that didn't exist when the caps were new is super silly to me. Trying to preserve a "vintage" point on a rapid downward trajectory of decay is only going to result in headaches for the tech and the customer.

Could you put an RC snubber across the HT secondary to reduce the power up surge?

Poke and hope wiring on that cap. Reports of those modern cap cans being really unreliable. Considering how expensive they are that sucks.

@@BradsGuitarGarage , NIN!? Better you than me! I prefer listening to the Dregs or the Steve Morse Band early in the morning. Take It Off the Top, Odyssey, or Cruise Missile are nearly as good as a couple cups of coffee for getting the brain and body in gear; or perhaps Night Meets Light if I need to ease into it gradually....

I’m to the point where I won’t look at an amp unless they agree to a $200+ possible budget.
