Mike, I did shake, tap and wiggle wires.

MrFixr, I can make voltage measurements without reception returning. There is no change. When I touch the 6A8 the signal gets louder and does not stay louder when I let go. I have wired in a aux connector without the switch. I will check to see if that play when the set does it's thing again.

I did not turn the set off but what bought it back was disconnect and reconnect the antenna ground. I wonder if this radio does not like my antenna. The antenna is about 100 feet of RG59 out to a tree. From there it splits off where the shield is attached to a long piece of rerod driven into the ground. The center connects to a 200 foot wire strung from tree to tree. I used RG59 to keep house noise off the antenna. I have used this same antenna on all my radios when they are on the bench. Without the ground the set is noisy.
