What is this odd little box I've been storing for years?
I received this switch/pot a few years ago with a used preamp and have never been able to identify it. When I asked the seller he said he didn't know either, he just thought it was part of the preamp (it's not). I wish I could post a picture here - but it's about a 3.5"black cube, with an older brown AC cord, an on/off rocker switch, fuse holder and small attenuator pot on the front. I though it might be a wireless remote switch for a turntable, but can't find any similar images online. Any ventured guesses would greatly helpful Glenn

Well, there’s an app for that!*

Ah! That explains it. (And I had wondered about the presence of a rheostat pot. eh)

Glupson, wrong. The second he throws it out he will discover it’s an indispensable part of something. I can’t tell you how many times I’ve done that with various seemingly unmatched Tupperware.
The shaft of the pot only turns 180 degrees. Inside there’s a transformer (EWC31004GO5), the base of the cylindrical fuse holder, the rear of the pot is a rheostat with a black resistor inline to the transformer....
The only thing I can think of at this point is that it might be a piece of test equipment, perhaps for the purpose of applying a variable load to the output of AC power supplies of some sort. The fact that the device does not provide an output would seem to rule out any other possibility I can think of.
HaHa! The worst thing is I can't figure out what to call it, to find a reference online. The shaft of the pot only turns 180 degrees. Inside there's a transformer (EWC31004GO5), the base of the cylindrical fuse holder, the rear of the pot is a rheostat with a black resistor inline to the transformer (no timer-but great idea). I had an old JA Michel Transcriptor turntable whose on off switch used a magnet to open and close the circuit.Wondering if this might be of that era (early 60's)
Might it be a timer of some sort? Perhaps when the knob is turned up to some setting and the device is turned on a motor drive causes the "attenuator pot" to work its way down to its minimum position, at which time a sound is emitted.
Are there any slots or other openings through which a sound could be emitted? Also, would it be practical to open the device and look inside?
