Then there is something not quite correct in either how you wired it or if it is an old pot salvaged from an old radio they had changed the A / B designation quite a few years ago.
The best way to tell if it is a linear pot is to unsolder it completely. Measure both outside lugs, this should give you roughly 10K ohms. Then turn the shaft approximately half way and you should measure 5K ohms between the center and each of the outside lugs. If the measurement is drastically different between the center and each outside lug, you have a logarithmic pot that will not work.
Also check the pinout of the trimpot you removed by looking it up on the net and make sure you have the wires to the big pot in the same configuration. Only if the big pot is confirmed to be linear from the first test.
I measured the pot from lug 1 to lug 3 = 9.56K then lug 1 to lug 2=4.11K then lug 2 to lug 3=5.42K.I double checked my connections they look ok pin1 to pin1 pin2 to pin2 pin3 to pin3=by turning the shaft clockwise the reading goes up and if i connect it reverse pin1 to pin3 pin2 to pin2 pin3 to pin1= by turning the shaft counter clockwise the reading goes up.The POTS are brand new from Chinada.THANKS!
