1125 Sample Hold repair

Greetings! I need to refurbish an 1125 Controller and I’m looking for some guidance on replacing the 3 Sliders and at least one 2-way switch with NOS or modern day parts. I’m not finding much info on the sliders other than one is 500k and the other two are 100k. Can anyone point me in the right direction to get these replaced? Thanks!

I replaced these on mine myself a few years back - sourcing them was hard. The 500K glide slider is ‘reverse audio’…!

The switches are the same as the ones on the smaller monophonics - Prodigy etc… eBay might be the first place to look…!?

Cheers,
Tom
