OK then, I'm guessing that the TAM is connected to the wall via a 2 wire
lead, terminated at the equipment end in a 4 way Western Electric jack. Swap
it for a standard 4 wire lead, then just wire the ring return lead from the
( previously unused ) pin of the 4 way input jack, to the corresponding pin
on the output jack for the phone. You then have the same scenario, without
having both leads going back to a splitter, and without having to graft caps
into the phone, although I still think that this would be the easiest way to
do it. I have put caps in on a number of occasions, to make three wire
phones ring on a two wire circuit. I can't understand why everyone's getting
so complicated with this - it's hardly rocket science ...
