What are resin capacitors and should they be replaced?
I’m just about finished refurbishing a Heathkit SB-401 amateur
transmitter that has, according to the manual’s parts list, five 0.2uF
“resin” capacitors. What are these things and how reliable are they?
Does conventional wisdom dictate that such caps should be replaced?
I’ve searched the web for information on this, but only get hits
concerning Black Beauty caps, which most always need to be replaced.
