Got the battery box sorted. Toggle switch and fuse, red LED power on light, 12vdc fan, and the voltages that will make the 20s radios I own work. The lug on the side is connected to the common ground, but I don't know if it's a good idea to use it. I've heard both arguments for and against it. I think I will take it apart now and give it a nicer finish and get a fan protector cage, but it works, and it ain't ugly exactly. Maybe my wife will let me put one of the 20s sets in the living room now.

For the record, I placed the LED across the third primary in series with a 10K resistor, and the fan just above C4 at the D3 output (which showed 12.47vdc on my mutilmeter). Please advise me if any of you see an issue with either placement.
