[R-390] AVC voltages revisited

[DJED1 at aol.com]

Just a tidbit for anyone else who is investigating the AVC line:   As I 
mentioned before, I disconnected the cable to the RF module and made some  
resistance measurements, which I thought indicated a leaky cap.  As I was  listening 
to the radio last night, I was browsing through the Y2K manual (a  great job).  
I was surprised to see that the RF amp schematic was different  than in my 
old TM, and the differences accounted for the irregularities in  resistance 
measurements.  Specifically, the newer manual shows a 1.5M  resistor from the AVC 
line to ground in the RF module, while the old TM shows no  path to ground.  
Since the new schematic agrees exactly with my resistance  measurements, I 
assume I'm all OK with the capacitors, and don't need to pull  the RF deck.
