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.

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.
