I need to test an Atari Audio/Regulator PCB and Atari transformer assembly.
I tested the voltages at the test points on the AR. If all voltages are close to ideal does that mean it is good or is there something else I am supposed to check? And what is considered close enough, as far as voltages?
(Perhaps it is better to just shot-gun the PCB either way).
Also how do you test an Atari transformer? I assume that you need special equipment to test capacitors, but I just swapped in a 28,999uf "Big Blue" and even though it was purchased a few years ago I assume that it is still good despite a slight dent on the side.
Since I get continuity on all the fuses how does one check the transformer itself?
The reason for all this is because I just blew a cap on one of my Millipede PCBs while trying to get the game up and working and I was wondering if a transformer and/or AR PCB that are working within parameters as far as measured voltage output could still be the cause of something like this. (I was reading that voltage that is too low or transient spikes cause a game board capacitor to explode).
Thanks.
