Chuck	Re: More general bias pot questions Hello Inquiring Minds, I haven't done this yet but I would try using a trimpot in a rheostat type fashion: tie the wiper to one end of the pot and put the two ends in series with the resistor that you want to raise the value of. I guess it depends on the values of the bias supply's resistors as to what value of pot would be best to use. On the 5G9 Tremolux (56K & 82K) I would put a 25K pot in series with the 56K resistor.
