Hello ,
I finally finished a 300B G.S.G. I fired it up but only the left valve is working. The filament on the right side isn't working, so I swapped them left to right and it's still the same.I tested the voltage at 6.3v from the trans, but no volts going to pins 1 and 4 on the socket. Everything seams to be connected .When I turn on the power there's a clicking sound, which I haven't heard on other amps I've made.Could the diodes be faulty?
If anyone has any ideas it would be good.
Thanks
