Balanced SET? North Audio


Has anyone heard of North Audio in Canada. They build SET amps that run balanced. They are bacically two single ended amps, one handling the positive and the other the negative signal. He says he owns the patent on this. This is why no one else is doing it. Could this be the ultimate.

Have you looked at Space-Tech on Renfrew and 2nd. He's another "garage" operation that is highly touted. Unfortunately, he's "on vacation" much of the year.
Herman, my own opinion, based on speaking to Steve a number of times, there is a great deal of, ah, exageration in many of his claims. I was not impressed.
Check out Space Tech. it is in your own back yard. I wouldn't call it a "Garage" operation but his shop is by no means a show room, far from it. He just got back from vacation, was gone a month to China and was trying to steal our audio sercets back from them!! LOL,he,he. Other than that he was off 2 weeks this summer. Hey the Man works hard he needs to play to.
Glad he made it back, I got my new preamp now and I'm just a very very happy custmer.
If your in Vancouver You must check them out!!!
Herman, Thanks for the straightforward elucidation. This guy must be the PT Barnum of the GWN. His prices correlate w/ Barnum's platitude, eh?
We've done something *like* this for the last- 29 years? or so... (of course we got rid of the output transformer too). What we found was that to be effective *every stage* in the amplifier had to be summed in balanced mode- in effect every stage had to be differential.

The North Audio sounds like its a push-pull amplifier. If I recall right Luxman made an amplifier that would have to have had a lot of similarities back in the 70s. It even had a triode output.
