Thanks Darcy,
I purchased a Knowles Voltronics sapphire trimmer with a shaft, but the shaft
moves in and out, which makes coupling to the tuning rod complicated.

Hi Shawn,
Have you tried looking into suppliers for Knowles Voltronics capacitors?
I’ve had success with Mouser Electronics before:

cheerios,
Darcy

Does anyone know a good source for old trimmer capacitors? I have two Varian
OneNMR probes that have broken small trimmers, <10 pF with a turning shaft.
Most of the trimmers I find have shafts that screw in which cannot be directly
swapped.
Also, if anyone has a source for used OneNMR probes, I am looking for a 400=
MHz and 500MHz probe.
