[Hallicrafters] 50k pot with DPST switch

[Julian Bunn]

I'm having surprising difficulty in hunting down
a 50k linear taper pot with built in DPST switch,
to replace the one missing for the ANL on my SX-28.

I've looked in the usual places (Mouser, Jameco,
Digikey etc.) with no success.

Does anyone know where else I might find such a pot?

Thanks!
Julian
