Hello all,
It's finally time for me to replace the original filter caps in my SB221. A
few questions:
1) Total capacitance with stock caps are 25uF (8 200uF in series), should I
increase capacitance to minimize voltage drop under load?
2) Are the 105C rated caps worth the extra few bucks over the 85C?
3) Are the different series choices only a reflection of the temp ratings or
are there other differences as well?
Note: I've already replaced stock equalizing resistors with 100Ks. Also
using a Peter Dahl replacement HV transformer.
Thanks for your suggestions,
Barry Norman KF4WGR
