Sure, why not? As long as the technical specifications (capacity and max voltage) are correct, everything is fine.Could one use a wima box style cap in its place?
Of course, but often box caps have very short leads.I could lay it flat across the pcb and bend the leads. Or is that a no no?
just dont wanna blow anything up. ill give it a shot. i like to order through mouser or digikey, but all they offer are capacitors that the datasheet says are used for "general purpose" or "motor drive" or "high freq switching"...never anything for audio. Things like this...Of course, but often box caps have very short leads.
I generally use 200vdc rated coupling caps in tube mics , mainly to save space ,
normally your dealing with less than 100v at the anode , if you apply power without a tube in there chances are you could exceed the rating , if the the heater goes open circuit you could also be in the same situation . Ive tested a few modern foil caps well above their ratings in terms of volts and they held up just fine .
Ero MKT 1813 250V are popular for tube microphones as they have a relatively small size, are quite cheap and do nothing wrong sonically IMHO.Which brand and model?
The answer is here Polycarbonate Capacitor & Replacement Alternatives » Electronics NotesI always wondered why polycarb caps have become difficult to source , the material itself is widely used for all kinds of things , its incredibly strong and resiliant .
https://www.hificollective.co.uk/catalog/evox-rifa-cmk-polycarbonate-capacitors.htmlThese guys have a few values of PC caps available , mostly in the 100v range .
