Actually, I'm really interested in how this turns out, now that you're replacing the caps. I wonder how significant the tonal change will be.
It's going to be week before the new ones get here ... it's such an oddball design; if you look back in this thread ... I've never seen another schematic with electrolytics in the phase inverter ... If i can find something within range, I'm going to bypass the dud and fire it up again. I'd like to know something about what it sounded like before too ... and if there's anything else out of whack. All of the coupling/blocking caps will be Mallory 150s, Sprague and Illinois ... whoever has the spec values for the other electrolytics. The amp passes a signal ... nasty ... but it passes one. It was running when I bought it and again when I found the footswitch. One of the reverb pots wasn't working correctly although I've hosed a fair amount of crud out of them ... I have replacements but I'm hoping the originals are okay. It came fitted with Sylvania 7591s but I have a pair of matched/used TungSols ... expecting something like the Guild Maverick Lead; cleanish, sparkly, 6L6-style sound.Default said:Actually, I'm really interested in how this turns out, now that you're replacing the caps.

I think I read the same thing ... but here's hoping ... I have a matched pair of NOS Sylvania JAN 6V6s that ... well ... they might last forever. But if they do, they'll do it without ever once sounding sweet and pleasant. Let's hope the made they made the 7591s on a different machine!

They are Sylvanias ... bought in July/August in the midst of my tube-O-thon ... confused them w/ the 7408s which are TungSols. :mrgreen:PhillySteve said:Sheesh Juan, you ought to try lookin' at the 7591s before you post ... or get some of that Memory-Aide ... :wink:
