I actually got to talk to the father in law yesterday, after I called the power company asking about 3 phase. He asked "how many wires are there on the top of the pole, the ones with insulators?" I said 1. He then said find out where there is 3, and that is where they would have to start wiring from. OMG! 2 miles! Can't wait untill the met ed guy calls with a quote, that ought to be interesting... Sir that 10kw 3 phase line is going to cost you 1.5 million, will that be credit or certified check?

I know people who have 3ph. at their own company, but here it would have to be generator or windmill, havent got the right plug yet to go into the avitar. So, heatsink problem eliminated, power supply torroid style 3ph 2-3K custom. Tdk style 13.5k. I think I'll take the 3ph custom (thanks rodeodave!). Now it's just the 50 pound amp. Ampzilla of the 21st century!

I do hope one day Mr Pass gets to hear an sit-1/250, if I had the parts I would make it for him and I would buy the garden hose. And that application could use the 2u genysys which is cheaper, and they have the variable fans. That whole amp could be carried with the power supplies by 1 person, heck I want to hear it too! Smile
$6700 pr PSU? well. and you need 2 pr ch. they are only single voltage supply's. you will need 2 of those supply pr ch to get +/- voltage. so 4*6700= $26.800. and thats only the PSU's what a waist of monye.

We bought this 1.5 acre place for $189k back in 2002. I love it here, 2 ft tall woodpeckers, 10 to 15 deer a day you can almost pet. The bear scared my cat to hell.... My wife, did what she could and I love her for it, there is work to do, ttyl and thanks... GLORY My aleph is at input 195w input, and rocking the RF-7 s. Im afraid to turn on another coupler of kw of svs... Wifey doesnt like that, neither does the house.... If you ever want a vacay, your welcome to stay here for free..

No you only need 2. I don't need 30kw... Besides the custom 3ph torroids and caps are relatively cheap, I did my homework... :-) GAME OVER coming soon. Of course wifey is leaving soon, there goes the nails in the house.... Thank god the skylights are busted already, I hope the paint on the door doesn't weld itself together, so I don't have to kick the door open, I've done it more than 1x

and how are you going to get +/-80V out of a single +80V supply? Magic?
you will need 2 of this supply's to form a +/- voltage supply.
and huge torroids and monster 80-100V caps are never cheap.

no there 200v at 50a ea What caps? No need... Even with the 3ph torroids, not many caps... I guess you don't read a lot, there is no need for anything but the tdk's. They take care of everything, worry about the amp... Sure 2 3u's cost 13k+ but they can run anything you ever had a wet dream about...

I can't see straight again....

AudioSan is right, those supplies look like single rail, you could build a gigantic ZEN with that. Technically you can convert single supply to dual supply, but I don't think it would work for this application.

ps. the Aleph requires a dual supply. You would need two per channel to create positive/negative and gnd. With one, you just have postive/gnd.

You lost me, I talked with tdk yesterday, 2 in series are the rails, and theyre variable... KLUNK, Really? I spent 1 hr with them.... They can do ANYTHING, A set-1/250 and this amp in 1 shot, and anything you can imagine....... How much are you guys gonna spend on donuts and caps, and heatsinks? This is 2013, we can do it... GAWWWD Wake up More coffee, and more intelligence...

single supply: The website of the Genesis doesn't show the rear connections, but I suspect it's this type of supply.....This would not work for an amplifier requiring a 'dual ploarity supply'.
