Re: Replacing "micamold" caps in oscillator section
The Micamold capacitors are all to be suspect. I had a nightmare situation with them.
I was restoring a Magnavox B&W TV set and had H osc problems,
The shop had a box of NOS Micamolds and I tested them with an LC53 Sencore unit, a military capacitor tester, an eye type tester and a digital tester. They all tested perfect. I replaced the ones in the circuit with them and it still wouldn't work. Replacing them with new epoxy coated silver micas solved the problem. The other tech had the same situation with an RCA TV tuner, Caps tested perfect, but the Micamolds were punk.
IIRC, the Micamolds were all paper mica.
Since then, if a set has Micamolds in it they are replaced.
