Terry does GREAT work on those vintage radios, doesn't he? Icon_biggrin

Thank you, Terry, for pointing out that dual 370 pF cap connected across the bandswitch - that, too, will need to be replaced. The original is either mica or a very early ceramic affair, insulated only by a wax coating that breaks down over the decades. It is two 370 pF capacitors in one package; one wire is common to both units.

Terry, in my experience, nearly every one of those units has been bad and required replacement.

It needs to be replaced with two separate 370 pF mica capacitors - if you cannot find 370 pF, 390 pF will work well.

Do not use ceramic disc caps to replace this unit - use silver mica. Ask me how I know this. Icon_rolleyes
