Regarding the Silver Micas, are they the 4 trimmer caps on the 4 gang tuner? If so, can I back off the adjustment nuts and take the micas apart and clean them? I was able to align the radio perfectly, so I know they work, and the radio is holding its adjustment (no drift).

P.S....I knocked around every thing possible ( tubes, components, cans sockets, tuner, adjustment caps, etc and can't get the radio to make the rushing shooooosh noise, or have the volume drop. BUT, when it either of these things happens on its own, especially the volume drop, all I have to do is touch a grid, or even a ground point with a screwdriver, and the volume is back and it plays like a champ!
