Hello

Went to ohm the output transformer today, when I moved the wires, all of the insulation fell off of the primary and secondary leads !

All other wiring on the chassis appears to be in reasonably good condition, did note a resistor replacement had been made on the audio amplifier tube, with two 1 meg placed in series.

Also have to admit, had to look up on how to read the resistor codes on these oldies---LOL.

Also appears the audio output transformer may be driving a 5.5 ohm speaker ? So wondering if a replacement transformer with a high primary impedance and 8 ohm secondary would be close enough ?

Regards

Charles
