CLASS A POWER RATINGS

@dynamiclinearity

It’s hard, expensive and difficult to make a push/pull amp of any power that stays class A essentially all the time. The only one I can think of was the Mark Levinson ML2 amp of decades ago It was huge and yet only rated at 25 watts 8 ohms. But it had huge bias that kept it class A all the time even doubling into low impedance loads.

 

An excellent example of a pure class A push-pull amplifier. It was/is a beast.

?? Doesn't an amp's topography determine?

Why not just buy a Sugden amp and end it. You will no longer have a yearning for anything else....read up on Sugden, they were the first with SS Class A in 1967. No BS class A that transitions to class A/B....I had not even heard of Sugden, but a few years ago. My curiosity peaked, and I broke down and bought one. It set me back a decent penny

..but man I’m glad I did it.....A21SE Signature...once that was in place, I again broke down and purchased my Tannoy Speakers, now I’m in the poor house lol. I’ll tell you what, it’s one heck of a combo. You would not believe how good only 30 watts per channel can sound (40 watts into 4 ohm). I’m pretty much set for life, as I’m old.

The best class A amps have doubled their wattage into 4 ohms for at least 40 years.

I have a pair of mark levinson  33h mono blocks each one weighs over two hundred pounds they double every time the impedance  is halved and they are stable  to 1/2 an ohm. They stay class a all the time and when they were tested the output power was limited  by the input power. Each one the minimum  power requirements  are two dedicated  20 amp circuits.  They do not switch  to an ab amplifier  and there power doubles not halves as the impedance  is halved.
