The schematic shows this radio using a 2 megohm volume control with a 1 meg center tap. I measure the resistance between the two outer lugs and I see 3 megohms on my meter. When I measure between the center and an outer lug I see 1.5 megohms and it goees down to .7 meg with the control all the way clockwise (full volume) position.
is this poteniometer ok ? While cleaning the track I noticed one spot that appears rough while the remainder is smooth.
