Retubed my amps to glorious effect but one channel has a DC offset of 2v while the other is still at zero. Turning the pot near the meter all the way down gets me to 2v. As the tubes are set as two rows of six tubes next to each other, is the offset a discontinuity in transconductance of the output tubes from one row to the other? Will playing musical chairs with the output tubes possibly correct this issue?
Thanks in advance.
