I am restoring a Tek 475 that took an impact to the front of the scope. It broke some knobs and I know at least one of the pots is damaged. Part Number 311-1701-00, 20k with a switch that is dpdt. I know this is a modular linear switch double gang with a detent for the switching, but I cannot find any other manufacturers that make this. Bourns should have one, but it is not showing up on any searches.
Any help with what others have done to work around this issue would be greatly appreciated.

Thank you.

I thought you were referring to the Trigger Hold-off control, but that's a 311--1401. Which control do you mean? In any case, the vintageTEK Museum can probably supply the exact replacement part. Contact the Museum via contactus@....

311-1702-00 is the one I am actually looking for. R1070 on the Timing Board. It is the pot controlled by the red VAR knob in the middle of the A and B TIME/DIV and Delay Time control knobs.
I will definitely reach out to the VintageTEK people to see what they have.
This is by far the most complex restoration I have ever done. I have fixed up some old musical instrument amps and stereo systems, but that was limited to replacing caps and cleaning pots. This is a monster compared to those. Fortunately I have a friendly shop close by that repairs electronics and I think they can teach me how to calibrate it when I am done.

The vintageTek museum has been most helpful. They have the pot and some knobs I am needed. Thank you very much for the reference to them.
