The Amp Rebuild, Part Two.


After almost two weeks wait, the new transformer finally came from the good folks over at Weber VST all the way in Indiana. I promptly got the thing mounted in the chassis and started laying down the filament wires to the tubes and the connected the wires leading to the primary winding (the 120V side of things). 

Just to make sure my power transformer doesn't short out again, I connected the power plug to the the 125V winding, since my wall outlet read 121V. 
Brand spankin new power transformer.
6.3V filament taps to the power tube socket. These wires
are wound to and ran close to the chassis to
minimize noise from entering the signal path.
Filament wires to the preamp tubes. Pins 4 and 5 are
connected in series to create the 12.6V necessary
to run the 12AX7 preamp tube.
Up next: mounting and connecting the main circuit board and rectifier circuit.
