The Amp Garage

Hey guys, I'm installing the reverb on this amp and will post pics when it's done. I've got a quick question meanwhile though. I'd like to experiment with feeding the 6l6 screens from B+ rather than the stock ul configuration; however, this power supply would put about 500v on the screens as it is n...

Last batch of pics. I drew up this layout for the ppicf after some hemming and hawing--hope other folks can get some mileage out of it also, as it is battle-tested. I'd really appreciate any comments thus far. Thanks to everyone on the forum for their helpful contributions--especially Brandon and Ch...

As promised...

Thus endeth the laborious first chapter in my twin overhaul saga. Some background: I bought this amp—a 1980-82 master volume ultra linear twin reverb—used probably ten years ago. It was my first real tube amp! After a year or so I built an 18 watt (with the help of some great folks from that forum) ...

It's been said (by everyone), but that amp sounds awesome! Haven't been sure for a little while what sort of tone I'm chasing after and this put it back on the map in a big way. Certainly any great amp is a great amp, but I tend to prefer the character in that growl to the traditional compressed sou...

They're back! Thank you!

The pics are busted ... does anyone have them backed up?

My thoughts at this point -- The amp did replicate the guitar sound for a little while - without distortion. So, this seems to indicate that the problem is between the first and second preamp stages. So far I've only tried switching the coupling cap with no success, so I can rule that out. I've recy...

I left that triode unused.

I'm using a GDS 36watt PT and have used this same power supply before but with a 1k/25w wirewound as a choke. Rectifier's plates look bright too - what happens when a recto dies?

Swapped out the first stage coupling cap. Still no sound. How red is cherry red? ...

Would it be okay for me to get in on this as well?

Pics. No red plating as far as I can tell.

Nah, that was a typo. I'm apparently an amateur at typing also. Should be 232v. This means B+4 and B+5 are equal, which should not happen.
