I'm back to working on the radio this weekend. Here's the underside of the receiver chassis. It's a real PITA to get at the capacitors and resistors.
First up, I tackled the 5-section capacitor block.
I discovered that a small chisel is the easy way to pry those heavy steel tabs up without leaving much of a mark.
I melted out the tar to free up the old caps and expose the metal contacts.
I cleaned up all the parts with lacquer thinner.
Here are the new caps wired in. I'll be used some two-part epoxy to glue them down the the backing board.
Here's a dry fit of it all back together. I think I'll just stuff a little packing material inside rather than filling it with a potting compound. Never know if I might need to get back in there
I'll also be painting it flat black.
