The actual "Micamold" caps are supposedly more like ceramics, you can leave them alone in most cases. There is a visual way to tell the difference. I wish I could remember.......help!

Perhaps someone else who remembers this thread can make sure my version is correct, and we can refresh the subject for newer people.

Perhaps this will help. I posted this figure from an old ARRL handbook in my 7VT2 restoration thread.

It shows that true mica have a black dot while paper have a silver dot in the upper left corner.

FYI I had long ago in the past restored a Westinghouse 21" table model that had been in a flooded cellar for what may have been years. It was thick with mud all over the chassis. I hosed the darn thing out, left it in the sun to dry, and fired it up after re-inserting all of the tubes and applying tuner-lube to sockets and all of the controls. The set worked perfectly for two years before the selenium rectifiers let go, and stank us out.

But that was neglect. What you have there may have involved "tinker-bobs"--which can make for a troubleshooting nightmare.

Thanks Bandersen for the visual. Perfect!
