Well, I removed the 5.6 Meg resistor and the radio still works when it's not dragging down B+ intermittently. <sigh> So, now I go wiggling wires and tapping on the chassis, and EVERYTHING I touch causes a change. Just gotta love intermittents!

Still curious if anyone has heard of a "fix" involving adding such a resistor.
"Why, the tubes alone are worth more than that!" (Heard at every swap meet. Gets me every time!)

Philcos: 90, 70, 71B, 610, 37-61 40-81, 46-420 Code 121 to name a few.
Plus enough Zeniths, Atwater Kents and others to trip over!
