[R-390] Z503 Replacement

[rbethman]

I would expect ALL coils on the IF decks to be very different between 
the R-390/URR and the R-390A/URR.

Let us know how this works out over time!

> Hello Folks, Well, I went looking around here and found a partially stripped R-390A IF deck. The mechanical filters are missing but the Z-503 assembly is there. It measured around 23 ohms so I have installed it in the 390 IF deck. I haven't tested it yet as I have a limiter problem to sort out first. I'll report back when I have some results. Fwiw, It looks very different inside. I'll get some photos and link to them soon.  73's Ross W1EKG
