Hi Pholks,

This is a copy of the GE 574 Radio - Phono Volume Control.

It is a single pot with a grounded (to B-) center tap. Resistance between the 2 ends of the resistor body is 1MOhm. It is likely that the resistance between either leg and the grounded center tap is 500KOhm. I assume that the unit acts as a back to back audio taper. The midpoint of control rotation puts the wiper over the grounded center tap and is minimum volume for both. Unsure why Philco did not draw the control in the same manner.

"Do Justly, love Mercy and walk humbly with your God"- Micah 6:8
"Let us begin to do good"- St. Francis

Best Regards,

MrFixr55
