/diy/ - Do It Yourself

>>2739606
Not yet, but it's an old scope and I want to get backups for parts just out of principle. The two pots that are really dodgy are different, pic related is a 1k of the same model but the dodgy ones are 10k (and say 546 not 545 on the side). The service manual calls them:
>V12L5 (PVB) N10KOHM SHAFT18
The pot isn't mounted on the panel at all, it relies on the PCB mounting for stability, which consists of the three main pins but also a structural pin at the back. I can't seem to find one of these on octopart, or in the catalogues of Alps, Bourns, or Panasonic. Does anyone recognise this manufacturer's symbol? Searching for V12L5 pots gives me a few old multi-sectioned pots for audio stuff, but nothing like this. I gave the two bad pots a liberal soaking of IPA and a good twisting, we'll see if that fixes it but they're the vertical-offset pots for X and Y in an 80s scope so they're not going to last forever.
