My father, a veteran electric engineer gave it to me yesterday, just so, to try. He told me it filters out washing machine and other kind of noises pretty effectively, but it's a real simple circuit - as an engineer he doesn't believe in different sounding cables either, if within an acceptable thickness and quality copper.. so he's absolutely on the anti snake-oil side. He saved some (not much) good old NOS stuff from scrapped mainframes and other kind of old computers, measuring devices etc. while he was working (these have already landed at the garbage collector at that time so all such things were sent for destroying/recycling, .. back then about dunno, 10 years ago, 15 ?)..Where'd you get it from?
Anyway, he has just stumbled upon this device in his back garage and thought he gives it to me, knowing I'm making myself familiar with electricity and Arduinos nowadays. (Basically I'm an IT guy). I think I'll use it for my PC's Genius 2.1 hobby hifi first, I always hear a pop when somebody opens the warm water tap (the circulating boiler starts to heat) and then again one when it stops. It's a rental flat (yet, but moving soon into own house) so we can't completely redesign the in-house electricity here, although pretty new (10yrs).
Anyway, just thought I'm bringing it into this thread for fun and to laugh but if it turns out it's even useful, woo-hoo. It's really looking and smelling oldschool, built like a tank. Otherwise not big, about 10cm on the long side.
Edit: called him right now, it's from an old Russian industrial computer.
