I'd have to dig though my old mags and documents to be sure. But I'd
guess it uses DIN sockets and has a line sensitivity of about 500 -
100 mV. So would need some resistors to cope with modern line voltages
(circa 1V to 2V).



I would be using the Tape Recorder Input on the Goodmans. Physically, I
can get the signals there, after a bit of soldering. Interestingly, the
DIN socket from the dead donor cassette deck has a bunch of resistors on
the DIN socket board, but I can't see what colours the bands are, they
are hidden. At the moment. I have a DIN-DIN cable already, it's a matter
of getting the signal to it that requires the soldering and construction
of a connector. This is possible.


A possible complication is that the original DIN specification included
that the signal should be a *current* source. Not everyone was mad enough
to impliment that, and instead went for voltage. So you can easily find
items from the period that aren't compatable with others unless there are
some 'bodge' resistors in the circuit!

Slainte,
