Does the hifonics thor VII & VIII use the same rail switching as hifonics zeus VIII

Hi, I have a quick question about the oldschool hifonics thor VII and thor VIII amplifiers. Do they have the same rail switching technology as the oldschool hifonc zeus VII and VIII amps used. Also what is the exact reason they used the rail switching technique . Thanks

It's used to be more efficient which requires less cooling, smaller sinks, etc.

I don't have anything on the thor amps you listed but if you can find a photo and see wires soldered to the transformer, it's a vari-power amp. The attached photo is a series 6 odin. You can see how the windings are tapped.

Thanks Perry,You are always very knowledgeable ,and have always been a great help. Thanks again

So the rail voltage is switched down/up according the load?
I have a Hifo Collossus VIII with +/- 75V; +/-50V and +/- 25V printed on the board with a non working channel ;-)

The switching is done only for signal level, not load impedance. The attached image is from an Earthquake amp.

So class G technology.
