Some times the parts you need are not made any more so that makes the search more interesting. In this case, I have seen the parts that woould work for this gizmo we are talking about. It was at least 10 years ago but it is quite likely many electronic hobbyists will know something about it. Go to an electronic swap meet and ask around. I don't fool with that stuff any more but if I hear of something I will post it here.

Thank you, Sir!
