Re: Power supply build quality pictorial. part 2
Probably a current rating in the same ballpark as an MJE13007 BJT, just much faster rise and fall times, and no storage time (three factors that limit BJTs to switch frequencies under ~50KHz).
Yeah, I think the ESR of KY may be low enough to cause stability issues, and the ESR of the FM series is even lower. I'm assuming the impedance of those JP caps is in the same ballpark as Nichicon PJ or PW. Nichicon PW, UCC LXZ and Panasonic FC are pretty much equivalent parts, in terms of impedance. Were this P/S more modern, needing lower impedance, KY, HE and maybe KZE or FM might be appropriate. That's just my (very) mental guesstimation.
