Hello. I have a problem and not know where to start.
A friend and I have built a Tweed Deluxe and it seems that something is wrong. Up to 3 sounds amazing, clean and with amazing harmonics, but when it passes from this point that an overdrive / distortion rare, no music, which only affects the low notes, especially the chords on the sixth string. It's like a crackling/farting loudspeaker. At first it was thought this could not stand the low that makes the amp, but I've tried a Celestion Blue and a vintage 30 and remains the same. I used the method of Hoffman masses. The welds are all clean and shiny. I checked all the voltages across the circuit and everything is correct. I have a 360V B + I got Zeners adding a couple of 12v to the center tap of the PT.
Resistors are NOS and some exceed its value between 10 and 15%).
At the start we had an oversight and the power amplifier was or a couple of minutes without connecting the speaker, but I think it has damaged the OT, did not smell or smoke and output swichcraft connects the ground and positive if the jack is not connected, to prevent possible damage to it.
The only thing I can think of is that a capacitor has failed, but not by which begin or how to check.
I hope I can help.
