For those of us who have the awful habit of restoring vintage equipment with non-polarized convenience receptacles and who often have a hard time finding replacements - These fit Dynaco and similar products.

Good find! I haven't seen those in years. I forgot about Philmore making them.

Update: These fit as-found in a latter day SCA-80Q. I had to file them down a little bit to fit into an SCA-35. Fastener spacing is dead-on, and there is plenty of clearance inside in both cases.

shack.

Interesting, I have many NOS ones that I picked up from a Philmore
distributor. Guess I should put them up on my web site...but they will
be more than $1 as I think these are actually UL/CSA approved.

As these would never be stand-alone devices, they should carry a UR (with the R reversed) designation. And, yes, that would be handy.

Anybody know the history of that symbol? It's cool looking, and seems to
be something beyond what UL would ever come up with on their own.

Start with UR. Run the letters together. Mirror image it left-right.
Slant it like a back italic.

UR is a UL recognized component. They are tested to a UL standard, but
to use the component in a UL listed device UL has to clear it for that
device or class of devices. That may include conditions for its use.
