[Collins] 75S3 S-Meter Problem

[Bill Stewart]

The s-meter on my 75S3 worked ok after I did some minor repairs 
on the rcvr...that's been several years ago. But now, set up for CW 
and RF gain at max.(full CW position), the meter pegs to the left pretty 
hard and I stopped using the rcvr fearing damage to the meter. The RF gain 
has to be turned back CCW a good bit before the meter will come back, 
off the LH peg, to the zero mark. Now I wanna get that rcvr back on 
line. Before I go into it, I wonder if anyone can point me toward a 
possible fix..could it be just an internal adjustment? Tnx for any guidance.
