[Amps] Right mounting of HV oilfilled C's?

[Karl-Arne Markström]

The "K-film" marking and the capacitance/voltage ratings "rings a bell".

Your capacitors may be designed for heart defibrillator use,
and those are not suited for filter capacitor service.

> I can send pictures of these capascitors, if necessary.
