Communications headset tester

[skimask]

Ok,
so i guess it's probably miles away... or not. mmm, all beltpack/base station etc etc, were connected together via 3 pin XLRs. They called that Party-Line.

Try to draw a schematic of your existing tester board. It may reveal some interesting stuff. Same for the transistor board on the headset.

Sure it's doable... If it worked.. it can work again.

Don't give up!

That's just it. The tester box itself is almost stupidly-simple, just an LM386 amp. Shouldn't be a problem with that right? Not so much.... As near as I can figure, the guy that designed/built the tester box is probably around 115 years old by now. Not much of a chance of getting useful info from him.

And the schematics will come next week sometime. It will probably be clear as day as soon as I draw it out.
