[R-390] R-390/URR Z-503

[Tisha Hayes]

It looks simple enough;
Tuned Circuit, Intermediate Frequency: 455 kHz center frequency; Including
L514 and C563, (13499) drawing no. 278-0235-00.

I have a spare good IF deck, this weekend I will open up Z-503 and unsolder
a leg of the cap, take measurements of the capacitor and the inductor to get
some values for what L514 and C563 are.
