Hey folks, I was looking over a vintage SVT pre schematic this morning, and had a question about the ultra-lo switch on channel 2. The schematic seems to indicate a connection between the wipers of the switch, but it looks to me like that would short around the volume pot: Is this a...

Up and running! Thanks for your help. [Invalid or Expired Link Removed]

Wow, nice build, B-string. I guess I'll start by trying to google around and source an appropriate epoxy. If I can find that, then I'll try to save up some mechanical patience for the fiddly bits of the build! :-)

Thanks guys. I actually ordered one of the cinch dampers in my last order from fair radio, having seen Beans' recommend previously on that other thread. But despite this, the 6C4 I had in the amp continued to worsen, to the point where it would make a loud pop if the preamp chassis was jostled...

Hi all: Does anybody out there have a wiring diagram for a Gibson EB-2D? I am trying to revive one that I recently acquired. In particular, I'm curious about a cavity beneath the bridge that contains a large rectangular component potted in wax. Is this customary for an EB-2D, or perhaps...
