Wiring a subwoofer to monoblocks

I do not believe the Audiopax are balanced.
As the spec it's two 15 watt amps wired in series to give 30
so I should be ok.

I suspect that is not correct, Simon. It may or may not be balanced in the sense of processing out-of-phase differential signals through its internal signal path, but the fact that the secondaries of its two output transformers are apparently wired in series tells me that the two output terminals are most likely balanced (with neither being at ground potential).

In any event, as I indicated above, no harm can come from trying it with sub black connected to amp chassis (or to preamp chassis, as Hevac suggested). Just don't connect sub black to amp black unless you are totally certain that amp black does not have a signal on it.

Thanks Al,
I really don't want to do harm to the Audiopax as I called in every favour I was ever owed to get them (a nice man on here who will remain nameless).

I hasten to add the reference to Jim was only because I know people who know him and I knew he'd know cause people I know that know,well when it comes to pax or avant garde - he's da man! so I said his name and crossed my fingers:-)
Email on it's way Jim

Rgds to all Simon

Hi All,
nothing is a problem when you know how!
Big thanks to Jim Smith - I have the knowledge,
all I need now are the connectors/cable...
and another Quake :_)))
Will report back when it's hooked up.

Made up cables and hooked up the sub yesterday.
Not expended much energy setting it up but already I'm over the moon with the results and can't wait to pick up another for a matching pair.
Seems to let the amps really sing, opens everything up and
real bass to boot -result:-)
Thanks for everyones input.
