Thanx to all who responded, and
Thank You Terry, you are being most generous, as usual.
I`l send you my adress off list.

Grounding issues have made me cave in, and look to optics, for the 
Musical TC trigger lead. I used to think Fiber Optics was really hard 
to do, but the 2 pin devices from Industrial Fiber Optics have changed my mind.
This is an application where I think Fiber solves a "real" problem: 
Back emf into the controller, In this case a Roland Synthesiser.

But also the ability to make or break a contact inside a faraday 
cage, or at a high potential.
Oddly enough, a simple contact closure circuit based on fibre, is 
unavailable from the "Kit" manufacturers. Perhaps because it is 
trivial to do for anyone who needs it?.

However, it is not at all that easy to get an overview of the 
different fiber types and terminations.....

Anyway, thanks all for the generous response to this thread.

Cheers, Finn Hammer, coiling in Denmark
