Speco Portable Signal Tracer
Hi guys;
I'm looking for a schematic to a signal tracer I've had tucked away in a shed for 20 years. It's a Speco Signal Tracer. The only reference to a model I can find is "Signal Tracer". It's a portable battery operated unit though. front: https://flic.kr/p/nFuMNm inside: https://flic.kr/p/nHvxUd I probably won't need a schematic; as the thing looks relatively simple. However, I don't know what kind of battery this thing was supposed to run off of. Still not an issue; but it'd be nice to know the expected B+ voltages. I know I had one; I just haven't gone back in to the shed to dig for it. Does anyone have a schematic; or know what kind of B+ I should run it on? The tubes are 1S5 and 3S4. -Jay
