RFZ V781 - Trimmers Replacement

[smilan]

Hi, I have a V781 with one channel that going out of calibration and becoming very noisy after 3-4 weeks.
After re calibration the trimmers it become quiet again until it get out of calibration.
I would like to replace the old carbon trimmers with new ones but I'm having a hard time finding the right size on Mouser.
Maybe someone knows the type / series of those trimmers and which modern components will be a direct replacement?
Here is the size of the trimmers:

Dont bother trying to find that one, replace with a modern multiturn.

This is what I would like to do, but I'm having hard time finding a modern one with those dimensions (at least I don't know how to search it on mouser website).

Perhaps a Amphenol PTC-15 Series Trimmer Resistor could be bent into shape?

..or maybe the PT15 Piher: https://www.mouser.dk/new/amphenol/piher-pt-15-carbon-potentiometers/

..both are maxing at L=15mm, but you can probably get away with extending center leg a bit..

Just buy a standard one on .1 inch centres, drill suitable holes in the board, and run wires.

No, please don’t drill holes!
Jakob is right, you can probably bend the legs to make them fit. This is how I’ve done it one my RFZ V341 preamps where the spacing was also a little bit wider.
