Bogen CHB-50 Rebuild

[physics]

Alright, new results, with calculations to come later. Short story is that one of my power supply design books states that for the characteristic in question, the Nonrepetitive Peak Surge Current, gives the acceptable RMS value (half of peak, in the case of the half-sine waveform used in datasheets) for the specified period of time. 1n4007's are rated for 30A peak, so 15A RMS over one cycle is the limit. I crunched the integral for RMS of a charging capacitor (assuming DC voltage source to charge, should be worst-case), plugged in my circuit values, and my bias supply's surge current is about 5A RMS. Well within 60% derating, so that should be fine. I'll post calculations 'n stuff later for those of you playing along at home, and in case I made a mistake somewhere.
