Trouble in paradise. While conducting long term testing on radio the volume/signal quality was fading in and out. When I touch the top of the center 24 tube, reception comes strong again. Swapped tubes, resoldered wires. All with no improvement. I did rewind the primaries of the second and third RF transformers. Any other suggestions? I looked, desoldered, and removed the first RF transformer and did not see/test any opens like I did with the Second and Third RF transformer.
