Hybrid - Tube / SS amp capable of sub 1 Ohm loads?

maybe the moscode 401hr could;I would talk to george kaye and see what he says or recommends.

Hi Pete:

I’m the west-coast distributor for Viola Audio Laboratories. Having said that, Viola makes two different models that can handle your requirements: the Symphony Stereo Power Amplifier (MSRP $16,000) and the Bravo MK II Reference Stereo Power Amplifier (MSRP $44,000). Both units are exceptionally high current designs.

Last year I hooked up a Symphony to a speaker that generally runs from one-half to one ohm. Though the speaker still wanted more power, the sound quality was incredible. If you are after a virtually inexhaustible supply of power, the Bravo is in a class by itself (this unit can also be bridged for mono). Last week, one of the Viola technicians told me that they just put a Bravo on the test bench with a one-ohm load on it – they run it up to two kilowatts output and the distortion was only at .3%!!!

Take a look at Viola’s website for a description of each amp. Feel free to contact me with any questions.

Regards,
Ken

Actually, there is an obvious solution. Rather than trying to swim against the current by forcing a conventional hybrid amp to operate into a load it was not designed to face, why not use an amp that wouldn't mind working into a 1 ohm load and simply use a tube preamp to get that great "hybrid" sound you're looking for???

I am using a custom built 6SN7 tube preamp to feed Nuforce 9V2 SE amplifiers. That combination would likely sound much better than anything suggested thus far and you wouldn't be taxing the amp's capabilities... Seems simple enough to me.

I second the Moscode suggestion. The amp has MOS-FET output devices, and they work fine(don't thermally run away)into low impedences.
