Re: Heathkit S-99
Hunts mouldseal paper types....I replaced the 600v polyester I’d originally used in these positions with some Hunts NOS “military grade” metal cased paper caps ...I tested these at working voltage beforehand for capacitance and leakage. I’m not into all the voodoo but it did seem to subjectively improve the mid range, can’t really explain it.
