I will be getting 7.30k LCR inductors from Dave. My original thought was
to use 4 x 0.1uF Teflon caps and pot them in something like bees wax.
The 0.01uF could be either Mica or Teflon. However, I am not sure
if I want to have both caps of the same type. Lately I am also thinking
about ordering 0.4uF Duelund CAST Cu capacitors through PartsConnexion.
However, Duelund CAST Cu is PIO capacitor which has worse DA. That
is why I am not sure if PIO is the best cap of LCR.
Did anybody try Duelund CAST caps in LCR phono?
What other caps produced good sound in LCR?

Personally I didn't like mica at all. My favourites are polystyrene or copper/teflon paralleled with a polystyrene.

I can highly recommend the jupiter copper foils for your coupling cap needs but building Naz's circuit is going to run you quite a bill. Like Tony was going to do, I'd start with the russian teflons and a russian KGB paper in oil for the 2Uf output cap (the .22 couplers can be jupiters)
