Threshold Stasis SA/3 4 ohm load

I have a friend that may consider an used SA/3 for his Snell C speakers. Those should be 4 ohm speakers and a bit hard to drive. How much power can a SA/3 put into such speakers?

Is there any information somewhere on how the bias concept is and how they are rated in 4 ohm.

There are rated 50W class A in 8 ohm. It is printed on the front and they seems to have relative high current ratings. 16A continuous and 80A peak?
It is a bit more than ACA.....which I will bring for the next visit just to have some fun.....

Stasis are single ended amps?
 
It is chapter "Stasis general" I should look at?

Stasis 3 and Stasis SA/3 are two different amps....as far as I can see....
Will have a look..... but today still a good amp. It was expensive stuff back then....I could only afford a Nad....
 
The only Stasis concept description I could find was this one.

The follower stage is push-pull followers?
So not a single ended design. Then the output power in 4 ohm is probably about double than in 8 ohm.

SA/3 is the only Stasis stereo amp.....so a kind of entry level Stasis but still a good one is my conclusion so far.....
