Hint:

A safe way to check for bad tubes that are either microphonic or shorting, wires that are not soldered, or cols solder joints, switches, controls is to make this tool. Take a pencil, remove the metal cap that holds the eraser on the end. Now find or purchase some small rubber grommets or thick rubber washers, be sure the inside diameter is a tiny bit smaller than the outside diameter of the pencil, slide several onto the pencil bottom with a little space between each. You can also use a Bic pen with grommets also. Turn the radio on (after it has been removed from the case of course) and Just start tapping everything until you find the area that causes noisy or intermittent problems, then do a visual inspection after you disconnect the radio.
