Did you adjust the RF AGC control?

Subject: [TechAssist] Sharps 25MT57 Tuner Reception Issues
Make : Sharp
Model : 25MT57
Problem : Reception gets grainy/snowy with static interference,
comes &
goes.
Problem is NOT vibration sensitive , we have pulled the tuner &
inspected.
Clean & checked AGC control.
Per one tip we changed C604 0.22uf but no help.
My next step (Which I haven't done yet ) is to inject IF after
the tuner to
see if see cleans up......but wanted to get any other input
from the group.
Any common things come to mind on this gem?
