Just out of curiosity last night I injected the antenna into the 3rd RF stage grid. I picked up faint stations for the first time!
I injected the antenna into the 2nd RF stage grid. I picked up faint stations for the second time!
I injected the antenna into the 1st RF stage grid. NO STATIONS WERE PICKED UP.
So I was able to isolate the problem to the first stage. The antenna tuner coil tested good. I retraced my wiring around this location. ENDS UP, I HAD ONE SIDE OF A BYPASS CAP CONNECTED TO THE ANTENNA TUNER COIL, WHEN IT WAS SUPPOSE TO BE CONNECTED TO GROUND.
I disconnected and temporarily jumpered that side of the cap to ground and the set is now working just normal! What a fool I am, but I guess that is what trouble shooting is all about.
NOW, HOW TO ALIGHN THE SET? I think this set is a Neutrodyne.
