I recently picked up a really, really inexpensive British Leyland branded radio with the intention of installing it in my MG. I can't nail down an exact date, but it's close enough to what would have been a dealer option(none were installed at the factory) when new for me to be happy with it. I have no idea who made it-Motorola made some of these, and there are a few Motorola components in it, but I don't known enough to say for sure.
I did some general clean up and after hitting the volume pot, AM-FM selector, and a few other spots with Deoxit, it grudgingly came to life and is actually working well now. At the moment, I have it connected to a nice bench PSU, and it's showing a draw of 100mA(which seems low, but I'm getting good sound out of it). It still needs a bit more cleanup, and the presets are sometimes a bit sluggish.
I'm not familiar with anything really of this vintage, and can seem to find little to no documentation on it. I think I've MOSTLY figured it out, especially after playing with it, but I'm still wondering about a few things.
For one, the hot wire coming out is wire nutted to a wire with a bullet connector(to plug right into the wiring harness) and also a lead with what appears to be a large capacitor. Most installations I've seen seem to put this on the ground lug on the back-does this sound correct?
Second, I'm not sure just how much I can drive in terms of speakers. I've been testing it with a speaker box that's marked 6Ω, and it's working fine. My car has two speakers installed in it, and I think they're 8Ω each. Both connected in parallel would be 4Ω. I'm wondering if I'd be pushing things to hook both up, or if I should stick to one.
Finally, is there a good way to figure out who actually made this in the absence of any clear markings on it?
