super high efficiency PSUs

MEGA-amp · 12th November 2003, 12:33 AM

At this point I am still up in the air whether I should build a Aleph 5 or an SOZ. I found power supply alternative. Just wondering if this would be a viable solution, take a look.

I find it conceptually appealing to mate the world's most
efficient power supply with the world's least efficient amplifier.

That would have one obvious advantage, you'd know that all that energy is consumed where it counts most, in the amp, not in the supply!

Yes. That will guarantee the whole amplifier will always consume more power than is supplied to it. Accidently getting this the opposite way around would be dangerous.

Reminds me of Steven Wright's comment, "I put instant
coffee in the microwave oven and went back in time."

Enjoy that claim while you can.

Anyway, anything without a heated cathode is relatively efficient.

Over at HeadWize some guys are cooking up 40-60 Watts of heaters and 30-40 Watts of plates to get 0.1 watts into headphones. Existing and worthy hollow-state 50W-heat designs not considered sufficiently extravagant. More Glow!

We'll see. I can run hot tubs and light and heat my house
while biasing up for headphones. And winter is coming....

And don't even get Cyclotronguy started...

I've got a dead-shorted compressor in my heat pump and a hard freeze coming tomorrow night.
Guess I'd better crank up the system.
Let's see...four channels of Aleph 2, a couple of Threshold S-500s, not to mention the odd Aleph-X, and a few experimental circuits.
Not to forget the tube amps--nearly as good as a fire in the fireplace. Romance in a bottle. Don't forget the crust of bread, jug of wine, and someone to help consume it, though that's a different sort of bottle. Just as worthy, in its own way, and nearly as effective for holding the chill at bay.

I was thinking about a pair of those liquid cooled aleph 1.2's to use as a winter swimming pool heater.

Often I enjoy the warm and hot things, saying, "Mmm... it's cool."
