Re: {Collins} Ceramic Tuning Caps Collins KWM-2

I'd like to know the answer to that question.  I seem to think that those trimmer caps can rotate without any change in capacitance if something gets stuck inside and rotates along with the trimmer, although I have no experience what so ever with it.  I73, SCott WA9WFA

I have read Glen Zook's story on taking apart the trimmers none of mine of frozen BUT is it possible for the trimmer to rotate and not go through its capacity range---like maybe the plated mica breaks loose? They look good to me no visible damage but no tune on 80 either. I have my HP 410C on the interface coax from the exciter rack to the grid of the 6CL6  on say 20 I get around 5 V RF and she's a boogie. Otherwise it has less than what seems to be the magic 5 V RF.  I have not yet deoxit'ed (is that a verb?) the switch looks like a PIA to get the shaft out and the cans off. Ted WA8ULG
