Repair or Replace Volume Control? Airline 62-181 (1931).

[Winky Dink]

I finally did a temporary hookup of the replacements for eight condenser block capacitors so I could power up the set. My first issue is a nasty volume control. After power-on, the first half of the sweep yields nothing, then loud crackling increasing with the audio volume.

The control was not made to be disassembled, and even if I managed to open the case I don't know if it would be repairable. I sprayed some contact cleaner on it, hoping it would magically seep through the seams. It didn't.

This is the part in question:

Is it possible to find a modern replacement (on/off and volume, 2.5Kohms, D-shaped shaft...), or should I look for used vintage components? I looked at Mouser and Allied but didn't find anything that I thought would work.

Advice?
