Default Re: Making a midi system cassette deck standalone

Thanks for the tips. Sadly none of the cassette decks listed there are close enough!

I have, however, studied the schematic from the system's amplifier and it seems that connector system control-1 is what goes to the tape deck I have. So am now trying to figure out the voltages that would appear on each pin 1-11. So far I have found:

1. GND
2. SSB TU (tuner controlled record remote?)
3. 9.1v AC phase
4. 14.5v AC (1)
5. 9.1v AC Centre Tap
6. 14.5v AC (2)
7. 9.1v AC 2nd phase
8. ? Rectified -29v?
9. ? -29v?
10. 5v?
11. 5v?

A further complication is that not al these lines are likely to be used by the tape deck , I think there was a graphic equalizer on the same connector. Will keep looking.
