[R-390] Parts Needed, new R-390A owner & questions...

[DJED1 at aol.com]

Welcome to the group, Steve.  I can't help with parts, but suggest you  
call Fair Radio and see if they have an IF module that's partially  stripped.  
I've had pretty good luck getting odd parts from them.   Otherwise, watch 
eBay for a junker IF module.  Fair may also have the  connectors needed to 
fabricate a replacement cable.
 
If I remember correctly, the mechanical filters should ohmmeter at about 40 
 ohms for each transducer coil.  If C553 is intact, then probably the  
filters are OK.
 
If your damage was caused by a shorted cap, then you might consider  
recapping the whole radio.  I did that a couple of years ago- probably the  
hardest part was removing the RF module.  Just requires patience.
