I pulled A4 1st IF transformer off the tuner to replaced the 15K resistor. It consists of the 15K resistor, a coil, and 2 mica caps at 10pf and 130pf.

Here is what it looks like:



I was expecting some "real" mica caps. Now I'm concerned that those caps could develop silver mica disease. I'm having some real trouble getting a cap reading on each of those with my cap checker. I could cut them in half and install real mica caps.

What do you think?
