eggs were sucked.....   <grin>    if it's wrong, it's Paul C's fault
as the Nanovalve with the speaker out is the one I bought from him
<LOL>  I've not actually added this to my other one yet.  You are
however spot on with the info about impedances.  The transformers on
the Nanovalves don't look like they'd tolerate much before going into
melt down.  I'm going to cut'n'paste your words onto the website until
I get round to drawing a cct diag for how to wire up an external
pspeaker.

cheers

now, isn't it about time we arranged a Scottish PU?
