[R-390] Wanted: R-390 IF Deck/Parts

[Jacques Fortin]

Hi Alex,
Despite being physically different, the Z503 parts in the R-390 and R-390A are electrically identical.
Meaning that a Z503 extracted from a R-390A IF deck can be used to replace the defective one in your R-390.
See picture of a Z503 from a R-390A.
Some other info about in the .pdf attached.
Just being curious: how yours failed ?
Is the winding test open ?
Can you provide some pictures of it with the cover removed ?

All,

Yes, the part in question is Z503 from the IF subchassis.  I have attached photos here.  I would be very grateful for any hints/leads on where to find this part!

Thank you,
-Alex
