No Load pot for Type 3 PPIMV

[Chris Brown]

I was about to use a push pull pot for the regular type 3 PPIMV, the one with the pot between the grid leak resistors, but then it occurred to me that a one of those "no load" pots that people use for guitar tone controls would do the trick. Turn it all the way up and it's completely out of the circuit! Works like a charm and the 250K has a much better sweep than doing it the 1M way.
