Hi. Good idea , I rewired reverse but now there is no control for volume at all, just high volume. The pot. is 1 meg very smooth in operation,and resistance. One side connected with shielded wire to grid of #75 det. tube. The middle connected direct w/ shielded wire to 6D6 IF output transformer, the 3rd end is connected to a cap to ground, ( which I replaced),and a 130K resister to a resister strip measuring 30 ohm to gnd. The tap of the pot. is connected to a cap. to ground which I replaced, also the tap shows good conductance to the middle connection on other side of pot.
