This one really brings me joy. You've all seen my stereo rig, which I described in Scotch Sampler. If you look at the pic below, the preamplifier (under the table) has a very rudimentary remote function (so as not to interfere with the esoteric-ness of the sound). There's an IR sensor in the middle, and the remote (on the table between the turntable and CD player) has 2 functions: 1) control the volume knob (on right of preamp), and 2) mute the output. Of course, it doesn't electronically adjust the volume, as that would add some shitty circuitry to the playback chain. It actually activates a motor to rotate the knob clockwise or counterclockwise, just as your thumb and index finger would.
The remote is - by far - the most ridiculously overbuilt thing I own. It's made of a solid block of anodized metal.
And after years of sitting around (and sometimes being packed and moved) it became corroded inside. So every time I want to tweak the volume, I have to get up and walk across the room, which is especially a pain when someone enters. But also, it's just frustrating to have to guess what the volume should be set to, because then I sit down and it's not really what I wanted.
Anyway, as a birthday gift, my stepdaughter got me a really cool rechargeable mini power screwdriver, which comes with a case that has like 100 different small bits. It's perfect for working on anything from eyeglasses, to laptops, to the tiny corroded Allen screws on this remote. I got around to trying it out, and I was finally able to take off the back of the remote. The batteries were all corroded, but also one of the wires to the circuit board was broken from corrosion. I've had a solder iron for years, but it didn't survive the last move. I could've brought it to the office, but Mrs. Scotch said "can you get a replacement"? Well I looked, and there was only one place that sold such obscure, obsolete stuff. Remote Control World, located in the Czech Republic.
To say I was skeptical is an understatement, but I did some research, and they seemed legit. I ordered the replacement 1 week ago, and here it is!
It's not an identical remote, but a replacement which performs the same functions.
The VOL +/- buttons smoothly rotate the volume knob, and the AV button does the "mute". Cost me $13 for the remote, plus $8 for shipping. It's been at least 15 years since I was last able to adjust the volume while seated. It's a great day.
