The question is what: What is the translation for RV4ATSA252D? Panel mount
is a yes, 2W is a yes, ¼ X 7/8 inch shaft is a yes. Taper????? I’ll also
dare to ask what is today’s replacement?

For a while I’ve been going through a too loud Amelco, 62 contract. Started
out with a bunch of could-bees and no ain’ts. Now down to the point of a
bunch of ain’ts and few could-bees. Swapped out AF & IF sections between a
Motorola and the too loud Amelco. Still too loud with Motorola stuff. Just
leaves the panel parts. Also rung out the wiring, nothing there.

Tnx,
Craig
