PSU Schematic
Trimoor:
Anyone have a schematic/circuit diagram for this power supply?
I can get it to switch the AC power, but no DC yet.
I can't find a model number, but the numbers on the transformer are as follows:
A037395-01Rev. A
142005-001
QK9-005RT-10
1W1ZP
Any ideas?

Wow, what does that thing power?
Just at first glance, I wonder if the round blue thing is a start capacitor. They are known to go bad with age. That should be easy to replace and they usually are $10 - $15.
Trimoor:
It's made to switch the AC power for the marquee and monitor, DC for powering the game.
I don't think it's a "start" capacitor, as it's one of 3 main components: the incredivly heavy transformer, a full wave bridge rectifier, and the capacitor.
The resistance of the cap increases when voltage from my meter is applied, so I think it works.

That is the power transformer assembly out of an Atari cabinet. Probably from a Dig Dug or Centipede.
Apollo:
I guess you've checked the continuity of all the wires coming off the transformer?
