[R-390] Looking for a 5-25 pF Trimmer

[Barry]

BTW, I "discovered" something this morning.  The screw "studs" that hold the can cover in place have #4-40 threads so I removed the two nuts and lock-washers, used some #4-40 aluminum standoffs (I happened to have 2" long versions) to screw back on to those studs, and used those standoffs to pull the entire assembly out.  That was SO MUCH easier than how I got them out originally.  If I'd done that, I think I would've avoided breaking that one spring finger from the mini-banana plug on one of the coils because the coils were so difficult to grip and pull out.  Live and learn.
