Trying to source a replacement volume pot for Tivoli Model Two

[securitypedant]

I have a Tivoli Model Two radio and the volume potentiometer has slowly given up. Just looking at it will cause the audio to drop out of one channel. It's 20 years old, and I could clean the pot, but i'd rather just install a replacement if I can. I've searched, but I can't seem to find a pot like this anywhere. Anyone here have any clues where I can look? The only markings on it are B50k and 5C4. There might be something underneath, not had chance to desolder it from the board yet.

This is similar. RK09L124000Z Alps Alpine
You may have to solder those snap-in tabs.

Wow, great find! That does look very similar. I'll go measure up and find out. I wonder if the existing one is linear or log for the taper. I think log is common for volume controls right? I think I can probably remove the existing and one test.

This one might also fit...

They're both volume controls, so both will have a log taper. The footprints look the same.
