This radio has been recapped and all OOT resistors replaced. When brought up on a variac with the volume control turned completely down, the radio will squeal loudly once the current draw reaches around 460ma. If I turn the volume up slighlty the squeal will stop, but returns has the current draw continues to increase.
I have not moved any wires except for extending 2 B+ lines to reach the new terminal strip holding the replacement filter capacitors, and these were run right next to the chassis. I suspect I might have a bad volume control but I don't know what the value of the tap is. Right now it measures just over 1 MEG on this 2 MEG control. The Sams, 15-24, does not show the value. The part is an original Philco part, #33-5535-1. Anyone know what the tap value should be? Thanks.
