Three 2.4kva circuits feed that room.

One is used to power the sources and pre-amp.

So that leaves 4,800 watts of mains power available to run:

i) the Fostex SS amp OR the 40wpc strapped LEAK St20s, and
ii)the two stereo sub amps,
iii) active HP filter and
iv) the two Eqr's.

Even with the slight inefficiency of SS circuits, and even with the valve amps draw of 200watts each in Winter - I don't think those two circuits will sag.

Feeding panels across the entire roof space there are two redundant 2.4KVA heating panel circuits. Some professional work would be required to redirect their cabling, and remove their timers on the mains power breaker box.

I would then have 4 x 2.4 KVA circuits to feed the power amps with!

Given all that spare capacity I have thought about going with balanced AC mains.

But I would prefer to do that first for the sources and pre-amp, using the existing 240V 10 AMP unbalanced circuit. It may be that an isolating mains transformer that also does balanced AC might be the best solution for the system's front-end.

Then there would be the task of dragging two or more big traffos into position under the house, and re-cabling to the wall outlets. Special wall outlets to meat safety laws and special wall sockets and differing plugs.

LBNL the various systems in that room have never been prone to mains-borne noise. Maybe I'd hear a lower noise floor but would it be worth > $Au2k?

Thanks I too would prefer to use parametric Eq, but the 1/3rd eq'rs were free - Timbo in Oz 00:21:45 05/13/17 (0)

There are a few different possible permutaions and combinateions for phasing a stereo sub arc with a gap - Timbo in Oz 00:46:01 05/10/17 (0)
