Aleph capacitor choice- elco vs motor start
I am pondering using 250uF 165V Aero M metalized polypropylene motor start capacitors in a mini A / Aleph 30. They will be bypassed with 56nF polystyrenes.
I plan on pulling "R19" so figured the larger "C10" cap wouldnt hurt too much. I could also change "R21". I am not concerned about the caps size, except as it possibly relates to electrical performance. Do I lose anything versus the Jleaman (thanks!!) supplied 220uF 35V 105C Nichicons?

The negative stuff Ive seen searching on motor starts was on electrolytic ones, these are not.
Ive got 92uF oil caps, but pairs of those would bigger than the rest of the amp combined. Also, lead length would be pretty long.
