In Reply to: Help with VTL MB185! No bias on one tube and resistors seems fine? posted by jjhf5678 on March 30, 2006 at 17:55:30:
It may be the bias pot, or something leading to it. Pull the output tubes and measure the voltage on pin 5 of the affected tube and compare it to the others. If it's significantly different you can trace it from there. I had a VTL 160 that had the same problem (intermittently) and it was the bias pot.
