while viewing your video of the apple iic power supply repair, it appears that you never provided -12vdc to pins 6 and 8 on J11. could you explain why you chose not to do that. Note; I believe the 1488 IC requires -12 vdc and there may be others. thanks.
while you're inside do a Rom 4x or 5x upgrade, you have the last revision of the IIC logic board with the memory upgrade slot

What's the relay switch for? Can you just run it without the relay and only use converters?
You can just use any 12V 20Amp power adaptor with a Center barrel positive.
