I have looked up a number of threads on this topic and get more opinions and more confusion. So I thought somebody here could help me. I have built the 6G2 a while back, sounded good, off it went to a friend. It came back for a to me just recently and I thought to check this thing with the plate voltages being unique in these amps, higher wall voltage, different power transformers, and my lack of knowledge when I built the amp. Not that my knowledge has gone up since, but effort to increase it a bit here. So I had purchased a Hammond 290CAX and used the 550CT, followed the schematic, but have a 12ax7 as the first tube instead of a 7025, but that shouldn't affect anything. I fired up the amp, all tubes in and working, speaker connected. Wall voltage 120V, 280V DC going to the 100K resistor on the plate of V1. All good so far, since this is what is on the schematic. After the 100k resistor I get 190V DC to the plate, not the 135V DC printed on the schematic. So is this a misprint on the schematic, or should I try and achieve the 135V on the plate, I haven't checked the voltages on the other tubes, just trying to deal with the V1 first. Does the amp sound good, yes but does it sound as the amp was intended, I don't know, I have never played a real one in the wild. Any thoughts, tweak it with some advice from here, close it up, nothing to see here and move on. cheers Ron.
