Hi Dennis,

I just put in a lovely post and the system swallowed it, drat..........
That voltage will give you around 200W from 65V rails. My only offering for that is the Maya, made for it, and five generations on from the original AKSA and better of everything; resolution, musicality, depth of image, natural presentation, silence, etc.
A pair of warrantied 2 year modules of the Maya would cost $2600 plus GST, but I doubt you'd ever need any more amps in your life after that!! In a proper enclose and fully plug 'n play, the cost is $5600, much more expensive, but I would assume you have a nice enclosure you are quids ahead...... expensive, but the best.

Ciao,

Hugh

Are these monobloc modules, Hugh? (So each needs its own traffo ... as Dennis has 2 traffos.)

Yes, Andy, precisely, it needs two 300VA toroids, each with two 45Vac secondaries.

Thanks for the info yes I have 2 very good thick aluminium gold anodised
"mono" enclosures with inbuilt heatsinks, is it possible to mono the Maya boards/power supplies? I did this with the power supply on my original 100n's

Just found a picture of the Maya, looks like to separate boards so easy to make monoblocks by the looks of it.

Yes, Dennis, it's set up identically with one 300VA for each channel, and separate heatsinks for each channel. You can build it very easily as a monobloc.

I can give your more information through aspen01@optusnet.com.au, easier to send graphics and photos.

Hugh

Been experimenting with bias, does'nt seem to make a lot of difference between 70 and 120mv with my speakers, lids back on sitting at 115mv, still little/no heat. Hugh will 400va transformers by ok with the Maya?

Absolutely, Dennis. Normally I use good quality 300VA, and never had any complaints! 400VA would give you more capacity with 4R loads.......

I think you have bipolar outputs, Dennis, and they need only about 60mA quiescent, and more is very little difference in sound. This is not true of mosfet outputs, however.

Cheers,

Hugh
