Hey all, I fired up a new 5G9 build and encountered some puzzling issues that I'm hoping some of you more experienced builders could help me with. Voltage numbers appear a little high but within reason. The issues are: 1) Moderately loud hum on startup, that quickly fades to a low level hum. This is without anything plugged into the input jacks. 2) With guitar plugged in, the bright channel barely passes a signal. The normal channel passes signal but the volume pot is silent up until 2 then suddenly goes to approx 3/4 of full volume. 3) With the somewhat working normal channel, it has a bad distorted tone. When playing a single guitar note there is an effect to the sound like a super fast tremolo— not like what I’ve understood as motorboating, but more like when you talk into a fan and it sounds like a robot This is at any volume. 4) The circuit board is very microphonic when tapped. Louder near the preamp area. Things I’ve checked or tried: • I’ve gone back through touch up soldering on all eyelets. • Depth and speed of tremolo circuit sounds like it’s working ok. • Tone pot seems ineffective. • I’ve swapped out V1 and V2 with different tubes with no change to the problem. • Confirmed good resistance values between the 4 input jacks and V1 tube pins. • That capacitor connected to pin 2 of V2 and the volume pot pops very loud when measuring voltage on it. Swapping this cap out made no difference. And pin 2 of V2 is very sound sensitive and pops/cracks when tapping it with a chopstick. • I built it as a clone, so grounded the filter caps to their cover. Tried rerouting the ground to the rest of the power section grounding point to see if it made any difference in hum, but it didn’t. • Tried different speakers Sharing some photos and voltages for context. Any suggestions on what else I could try to solve this would be appreciated.
