Thank you!

Tried swapping out the 6EJ7, but no luck. Tested all of the tubes on a tester and they test fine too. Think I found a resistor that has significantly drifted and ordered a replacement to try (right by the front-end bias test point, so that would fit with what I'm seeing). The caps appear to be fine and I'm a bit surprised given the amps age...guess driving ESL's are good for it. My OTL3 doesn't really match the schematics I have that well, so I need to try it to make certain that's the issue. I'll post what I find.

Thanks again!
