Re: 1st semi build express help
OK been reading the build guide. chord plugged in no guitar. Gotta hum. Am going to move the heater wires to match those of francesca. Do i need to put a resistor on the grid of V2 or is parasitic oscillation a different sound than a hum? IF i do need to do this that would be pin 2 right?
