Hey Ron,
I have the decals. They will go on as soon as I can elevate this radio from shelf-queen status .
Oscillating?
Here is where I am at. I think (I think) the radio is oscillating. I can pick up three very strong local stations at their appropriate spots on the band, though quite faintly. I have about 15 feet of antenna wire hooked up.
Also, I use my signal generator connected to the antenna terminal and I can "walk" the signal clear across the band starting at 1400 or so downward. I inch the signal down, tune it in, inch it down some more.
Right about 830, after a thud, the radio goes quiet, and I assume that is where the oscillator drops out.
But for the life of me, I cannot pick up the oscillator beat in a small transistor radio that I hold right up to the 36 tube. Could it be that it is not oscillating and I am somehow picking up the signal with no conversion or mixing going on at all? Do you think it is oscillating?
Antenna Coil
I have been working under the assumption that the antenna coil (2) is good, because I have continuity on the correct pins. However, when I make the connection in RED below with a jumper (bypassing the antenna coil), the signal gets quite a bit louder. Still not right, still faint, but stronger. Does this mean the antenna coil is bad, and I should be rewinding it?
I feel like I am making progress, but who knows?
