I'm restoring an old Magnavox era SVT for one of my customers. It was hacked by someone else (it would be blasphemy to refer to that person as a
"technician"

, and one of the pots was replaced with a junky off brand. The shaft of the pot is WAY too long, and it's not even the right shaft type. I need to find a 1 Meg audio (or log) taper pot with a short D-shaft (not a round or split shaft). I've scoured all the surplus bins of the local electronic parts dealers, but no luck.
Does anyone know where I can go to find a replacement pot (and other vintage
Ampeg stuff, should I need it)?
