No input/output jacks?
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

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? Regards, -- Al |
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) |
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. Regards, -- Al |
From your description, this box has only one electrical connection, a power cord. It reminds me of the "parallel line conditioners" of old. These devices were supposed to clean your AC line power. Two examples that I can recall are the Tice Clock and the Coherent Systems Corp EAU-1 Electraclear. Audiogon has lots of comments about the Tice Clock. Here’s one short thread -- https://forum.audiogon.com/discussions/anyone-remember-the-quot-tice-clock-quot-controversy?highligh... And here’s an old Audiogon listing for the EAU-1 -- https://www.audiogon.com/listings/ac-conditioners-coherent-systems-corporation-eau-1-electraclear-pa... Unfortunately, I could not identify your particular box. (Dunno if a pic would help either). Good luck. |
