I am working on a Philco Model 84. I did find the Cathode winding of the Oscillator Transformer open. I rewound that and now the oscillator is working.
When I put my finger or a long piece of wire on the grid cap of the Detector / Oscillator tube ( 77 ), I get stations very loudly. I have measured the volume control ( 1 ) which is slightly higher then 20,000 ohms. I have checked both the primary and secondary of the antenna transformer ( 2 ) and have continuity in both windings. However, when I touch the antenna clip or attach a long piece of wire on the antenna clip, I can not hear any stations at all.
All suggestions are welcome.
