I've managed to find some information, but many details are only available in the manuals—otherwise, I'm left guessing. I'm not expecting anyone to dig out a scanner, but considering how many units were sold, I'm surprised no one has simply snapped a few photos of the manual with their phone. That alone would be a huge help in finishing this build.
The All-In-One with tube rectifier is the manual I need.
