New Member + First Radio (Philco 60MB) = A lot of questions

Welcome.

First, let me tell you that plugging in the radio was a very, very bad idea. Please in the future try to resist the temptation of powering an antique radio that has not been recapped and fitted with a good cord. You got lucky but could potentially end up with smoke, radio destroyed, or even fire, house burned down, let your imagination run wild.

Now. When having recapped he radio, and the resistors checked, cord replaced (maybe it's good), tubes checked etc,  you will likely find out that some of your RF coils are open and have to be rewound. Philco 60 are known for that.

So. Start from maybe checking the power transformer.

I advised the owner against doing so but he ignored me. When I plug it in at home, I use a dim-bulb tester. I remember seeing that for the coils the material over time expands, breaking a piece of the winding and causing an open.

I want to replace anything that has a high risk of failing. If the resistors check out fine, is it imperative to replace them still?

When it comes to the power transformer, granted it is in good shape, is it okay if I soak the windings in Sprayon Electrical Insulating Varnish? And if the RF Coils are good, them too? Are they nichrome, or enameled copper wire?
