Micromold resistors

[JohnCT]

On another thread (asbestos related), I mentioned running across some weird shaped Micromold capacitors. Well, they aren't.

I finally found four schematics for this Emerson that are all similar, not exact, but close enough to work on the radio.

So these are little bakelite bullets that have "Micromold" printed on the back, and paint dots like the Micromold capacitors have, but they are in fact resistors. The length is about the same as a Micromold capacitor is wide.



These are the only type of resistor in the entire radio other than a big 175 ohm standup for filament dropping purposes.

Every one was bad, without exception, and I don't mean 25 to 30% off either. The ones that weren't dead open were ridiculously high in value.

A 250K resistor read 1.2M, and a 50K read 175K.

Oddly, the paper capacitors are original, they are also Micromold tubular paper caps (never saw Micromold tubular papers either) and every one is perfect. Usually, a .1 uf (for instance) would read .3 or higher as they older and shrink and have leakage, but these .1 caps read .13 or so and show no leakage at almost full rated voltage.
