Hey Folks...
Does anyone have access to a schematic or have working knowledge of
the above mentioned receiver...?
It has a weird sort of power supply set-up in it. There is 2 Power
supplies derived from 1 large power transformer, the + and - supply
for the output devices and a smaller supply on another board. These 2
power supplies are supplied AC primary power by a spst relay powered
by yet another (single ended) supply. The small power supply that
supplies power to the AC relay comes on with the front panel switch,
but whatever is supposed to energize the relay isn't doing it. I
suppose it may be a protection circuit, but it is tough to guess
without a roadmap... Any suggestions...?
Thanks....
