It did it s thing last night. Did a few voltage checks on the antenna coil. All were the same as when working except the one pin that connects to C2 (.05). Normal is -4.9 acting up is -3. Not a big difference but who knows. I did swap out with another new one.
R1 and C4 have been changed. All caps and resistors have been changed. Micas too. Just to make sure R1 (47mohm) is 47K and not 47 meg. I know M means K in these old radios.
Turned it on this morning with no reception. Replace C2 still no reception. Turned it off, disconnected antenna ground, turned it on and got reception. Funny how it always works after messing with antenna ground that connects to a rod in the ground.
Early on when messing with this problem when there was no reception I could get the squeal on a small transistor radio. So can the oscillator be messing up? I have not taken osc coil out yet. Maybe I should so I can have a look at it. Could that gimmic that is connected to the osc section of the tuner and wrapped around the antenna grid cap wire be messing up the oscillator? I had replaced both of those wires and may not have gotten the osc wire the exact length but they are in the same place.
I certainly appreciate you guys hanging in there with me.
