Thanks to all for all the great suggestions! What a resource this place is! But, like codefox1 said, "Unless it's something else..." And there always is. So anyway I opted to use Deoxit, toothbrush and dremel tool brush and I'm reasonably happy. Then I decided to measure it (gotta use my new cap. meter). 1st and 2nd sections tuned from 16 pf to about 390 pf. But the last section, when tuned below about 75 pf was OK and then it was erratic the rest of the way up - meter would not hold a value and jumped around + or - 20 to 30 pf or more. But the stator and rotor plates looked clean. However, when fully closed it appeared the outer two rotor plates might have been almost touching the stator plates. I know those things are "vented" or "cut" so they can be adjusted - by who and when I have NO idea. But I bent the ones that didnt quite look right ever so slightly and Presto! I got steady reading all the way through rotation. If I hadnt been messing around cleaning it I never would have noticed that. Here's a question tho: All three sections track +or- 2pf up to about 300 pf. After that they can be off from each other up to 5 pf. I dont like bending those plates and I am guessing that the trimmers will fix that at some point (if and when I get that far). Is that too much tracking variance?
