[Johnson] 10 Turn Potentiometers

[Glen Zook]

Looking at the schematic both of the balance potentiometers go back to the 200 VDC line.  The one from V-5 through a 47K resistor and the one from V-4 through the channel balance control.  They are both isolated through 1 megohm resistors to the grids of the 12AT7 tubes and are connected to ground through 4.7 K resistors.  Therefore, I don't see why a wirewound wouldn't work.

I want to replace the carrier balance pots on a Pacemaker. I don't know if wire wound pots would be suitable.
