Capehart Radio Restoration: Part 1


I purchased my 1942 Capehart Panamuse at the end of August and have yet to really do anything besides break one of the expensive power amplifier tubes. I've decided to change that this week, however, and I ordered the first set of replacement components necessary to make it run.

I'm starting on the power amplifier first, which is going to require a total of 18 capacitors to replace. I'm having to construct an equivalent capacitor out of two smaller ones for a value that wasn't readily available. Unfortunately, several of the vacuum tubes have leaked vacuum (evidence of internal corrosion on parts that are supposed to be nice and shiny) so I'll most likely be replacing all of them too. It'll be around $250 to repair the amplifier, and probably about the same to repair the tuner section. I'm still on the fence between repairing the phonograph and replacing it with a retrofitted touchscreen of some kind to play Internet radio. We'll see.
