Power amplifiers with selector Class of operation?

Hello to all,

Would like to know amplifiers that have the feature of select the class of operation, between Class A or B.

Like the Pioneer M-73, Sony TA-N88B, I think there's a Luxman too but can't remember..

Any others?

Thanks.

You want some like this, pity it isn’t made any more. 3w 10w 30w 100w of Class-A bias

Next best is the Gryphon Antileon Evo. low, med, high Class-A bias

And yes the Parasound John Curl designed Halo JC1 monoblock are great 10w or 25w switchable

Cheers George

I have a late 70’s Yamaha B-4 that allows switching between ‘A’ and ‘A/B’. The only discernible difference I can sense is about 50 extra degree of heat. Great sounding amp though.
