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!
