I have been poking around on this old dirty Connex radio and cant find the problem. It acts like there is a bad solder connection but that is not it. The frequency is all over the place as soon as I touch The center antenna lead or coil L31, L52 or L51 the radio goes right to frequency. It will also go to frequency if I touch the base or collector of the final or driver. I checked all the ceramic disc capacitors associated with the mentioned parts and they were not shorted. Any one have any ideas?
 

Yes all tight. That was the first thing I was hoping would fix It. I have been prodding and poking around on and off for a couple weeks and have never seen anything like it. No that I am a expert
