Hello, 

I am in need of a schematic for this radio. Mine has the three separate circular tube shields and a shadow meter also has a four wire condenser filter bank instead of the three wire. One speaker in a cathedral cabinet. The schematics I have (code 121 and 221) do not quite match my radio. The radio has a few cut wires and resistors hanging in the breeze. Anyone have the 125 schematic?

Thanks,
Dan

I noticed on the code 121 schematic the center tap for the 6 volt winding and hv winding are tied together. Is this correct?

Looks like that might be the B- buss, so that would be correct.

Really Rod? I know you would not steer me wrong but AI say this is a short circuit? What if I moved the 6 volt center tap to chassis ground. I agree the HV center tap is the B minus buss.

Reason I am questioning this is because I took the power trans out to replace the ratty wire and some how I forgot to note where the 6 volt center tap connected. Dang I hate when that happens.
