Even John Curl called them Motor Start caps in his thread, , but even he MEANT Motor RUN caps. Motor run caps are polyprop in oil- yummy!

My bad, a motor start cap is an electrolytic, motor run is polyprop foil.
I tried the motor runnners on the P1.7, not all that bad really.

(If it turns into a sour treat, at least i can repair each of the washers and dryers 200 times, should easily last me to the next millenium in my nuke bunker)

Motor run caps are plain metalized PP caps, but mostly better quality that the so-called audio caps.

Comar makes some of the best, and they happen to be cheap as well.

has anyone had a hum problem with the F4? i have a 2 inch ground bussbar with signal ground on one end and speaker and power supply grounds attached on the other end with the thermistor at that end going to chassis ground with power earth ground at that point on the chassis also.----i have tried grounding the rca grounds together and tried bypassing the thermistor but none of that makes a difference. my rectifier diodes are mounted a couple of inches from the output pcb --is this to close? maybe some stray ac? hum is the same in both channels and doesn't vary with all the pushing and prodding i do. please give me some advice -mark

Maybe you want to put all the power supply grounds on one end
and all the signal bearing grounds on the other end (including
the speaker returns) At this quiet end a power thermistor to the
chassis which is directly attached to AC outlet ground.
