Class A amplifiers - which are considered the best

What I saying is if a tube is run as SET/SET-P(parallel) be they DHT or pentode(KT-88 in this case) it can 'only' be done in full class A operation i.e. there`s no class B portion possible with SET design.

Hi George,
Reading the amplifier designer`s description says it`s made of 6 seperate 'single ended'(not push-pull) KT-88 all connected together and divided into two monoblocks.

Actually to be correct the design is 'six amps per side' for a total of 12 single end amplifiers.
Regards,

George ,
You certainly could be right about the class A vs A1 distinction. The designer does mention he`s able to get 21 watts per KT-88 tube as opposed to 18 watts per tube.Is there really much difference between the two types of class A ? I`d love to hear this very unique amplifier.

vicks,
Your amplifier is 'single ended' with the KT88? Are`nt SET amps pure class A by virtue of design(they can`t be class AB I believe).

Atmasphere,
I agree with what you wrote.
Push-pull can be class A or AB, flexability.
Single end is limited to class A operation only, no fleability in this regard.
