Cleaning out a closet recently I stumbled across a Radio Shack kit I built when I was just teaching myself electronics (2/25/80 according to piece of tape I stuck on the side of the box). It's a "frequency standard" -- a one-transistor oscillator with a 100 KHz crystal and a variable capacitor for trimming the output. Unfortunately I can't find the instruction sheet that came with the kit. As built, there are two wires (one each Red & Black) that come out connected to a power switch. I'm sure that the curcuit isn't very complex (total of 5 R, 4 fixed C, one Q, one Xtal and one variable C) and while I could trace it out, I'm not really that interested in the analysis of it as much as I am in seeing if it still works. But, without the instruction sheet, I don't know what voltage to apply. Yes, I could drag out a variable power supply and run it up slowly, but I was hoping that someone might either still have the instruction sheet handy or know what voltage it requires. (I tried a single AA cell and got no oscillation; I can imagine that it was designed for 5V or 9V or anything inbetween).
