Well, back on topic, and me being the cheapest of all with
no test gear I'm going to start cutting holes in wood and make up a
small isobarik.. maybe play it with no mains just see if it is
doing anything.

Far as I know this will be plug and play and whatever cutoff will
be handled by the receiver. With a phono plug connection I'll
prob'ly buy a phono plug one end and bare on the other rather
than fooling with tinning and such.
