Working on a Hallicrafters S22R. This radio has had some previous work done. Some of the molded paper cap replacements are cylindrical (white) and labeled ELMENCO. Any experience with these as to longevity?

Hallicrafters used alot of el-menco.

El-Menco was an independent company. Hallicrafters did not make their own caps. Their practice was to save money in manufacture by designing sets to use inexpensive mass-produced parts intended for ordinary consumer radios.

El-menco was originally most commonly associated with mica caps; later on, after they merged with Arco, they brought out "Brown Drop" and "Black Drop" equivalents to Sprague "Orange Drop" caps. The trademark for these is "EM."

I find no difference in longevity between El-Menco and any other reputable brand.

Electro-Motive Engineering Co. originally, I think.

You'd better check them; some of them are leaky now. I just ran through some caps with the Telohmike, and did find a couple of bad white Elmencos.

Right. You'll find the full brand name on numerous small chassis-mount variable "trim" caps they made, usually about an inch square with screw adjustments instead of a shaft for a knob.

The white EM's are plain old paper caps inside.
