Cap reformation question

At 06:25 PM 12/6/05 -0600, you wrote: sometimes you have to disconnect a wire or two, but not always, and the resistor gives you a degree of safety a straight variac wouldn't. That's what I was thinking of doing. I keep a bunch of HP adjustable voltage/ adjustable current supplies around and they've come in handy for LOTs of different things. (I used one tonight to recharge and test some lead-acid batteries for my HP 5315 Freq meter then used to same supply to manually drive the VCO LO in a spectrum analyzer that I'm working on.) Q: How high of a voltage do you use the reform the caps? I'm wondering if it's necessary to apply full (or nearly full) rated voltage or if they're fully reformed at say 5 VDC. Has anybody done any testing in this area? Joe
