1) It does not play at first power up of the day most times. Sometimes plays for over 4 hours without issues. So I guess that rules out temp.
2a) I have prodded, poked wiggled all connections and wire quite hard and gently. Will do again.
2b) No change while playing normally.
3) Voltages between quit and playing remain the same on Candohm. Freeze spray does not alter the reception. Voltages are -2.5, -4, -22 going away from ground.
4) Have done just that moving those control very slowly and rapidly.
5) I have just done that and no change.
I think the clue here is removing the antenna ground while powered on restores reception but I don't know what it is telling me.
Also I have stated before the AVC voltage does not vary much between strong and weak signal. Around -1.7 (strong) to -2.2 (weak). Is this a problem? Seems to me it is.

Yes there are rivet terminal strips and eyelets and I have run a wire from them to new ground connections with screw and nut. I have measured them all and they are at .4 ohms. My Fluke rarely seems to read below that.
Yes I replaced the 6A8 grid wire and cleaned the connector. The wire is about 5" long from top of antenna section of tuning cap to grid cap of 6A8 and has a gimmic wire on it from the osc section. So would the shield effectively disable the gimmic? The 6A8 is metal and yes pin 1 is grounded. The tubes shields are both missing with the 6K7 being the other one which has pin 1 grounded.
