Hello,

Pic is from a Fisher mono receiver, chassis 60, from a console. Can anyone tell me (1) what is the third (white) wire for on the speaker plug (far right)?, and (2) what are the wires between the speaker wires and the power cord (the wires with the ends leaning up against the transformer)? Also, am I correct in assuming that yellow/black = +/- ?
Unfortunately, I haven't been able to find a photofact or a manual, and not technically apt enough to figure out what's what by following wires backward.

Thanks for your help.

You said the amp was used in a console system. Do the speakers have two leads going to them or four? If the latter, the speakers use a field coil instead of a fixed magnet.
