Re: Help with VTL MB185! No bias on one tube and resistors seems fine?

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.
