However, after I stripped the radio and preamp out of the unit, I started looking at the output and power supply and started scratching my head. For one thing it has external speaker jacks on both speakers, which have little transformers and a switch. I sketched out what is all was and it didn't seem an clearer. For one thing the jacks themselves seem to be switching jacks but I couldn't find any wiring setups for old 2 pin DIN sockets. So i just drew it the way it seemed right.
Anyway, If this output seems usable, i"ll just build a preamp into it, but it seems wierd.
You can't see it very well, but on the tabs on the back of the jacks there is a "-" symbol on top of the one to the right, and a "2" below it. There is an "8" below the center one and a "4" below the far left. I thought it was for ohms but all four speakers are 4ohms and seem to be wired in series.
I was also wondering what the point of the 1n couple capacitors on the output transformer primaries.
