[Amps] First Power in 25 years question

[Tony Brock-Fisher]

Non-6100 specific advice:

The big concern is primarily the electrolytic caps. Depending on the power supply design, you could first pull out the rectifier tubes (assuming its not solid state) and power up slowly from a variac watching for smoke. Bring it up slowly, 5 volts every 5 minutes. If all is well without the rectifiers, turn it off and plug them back in. Repeat the slow power up, but maybe give it a long time around 80VAC (or whatever line voltage gets the rectier filaments hot enough  to start making HV), maybe 24 hrs. Check for appropriate voltages out of the power supply - if any supplies are not coming up, suspect a shorted cap in that one.  You want to check any electrolytics carefully during the process. Feel them (watch out for HV on the cans) to see if they are warm. If they are bad they will get warm/hot, and may start leaking, or even go bang.

Good Luck!
