I am using SA11 + SA111 gear. I have both Thermal and Agc"s . The thermals range 3-9db. What is the proper set up for the thermals? I know to duplicate my manual levels when using the Agc's. Also which ground spring is the one that causes all the trouble when my Agc's act up, the top that presses against the cover or the side spring? Thirdly a lot of the techs here don't use all of the screws
in all when putting the cover back on, will this cause any response problems????
