Anyway, the machine itself works fine, however the
Atari SC1224 monitor that
came with it does not. I can hear it "chirp" when I throw the switch,
suggesting
What sort of power supply does it use? If it's a switcher, then the chirp
might be coming from the chopper transformer, indicating, perhaps, a
short on the output of the PSU. That, in turn, might be the line output
transistor (HOT to you, I guess).
