Sophia 300B vs Jeff Korneff 45 Amp

Anyone have anyway of describing the sonic differences between Sophia Electric 9101 300B monoblock single ended amps and a Jeff Korneff 45 SET amp? (Let's assume the JK 45s have enough power to drive the speakers at around 100dB efficiency.) Thanks

- a related question would be which tubes would be preferred, Sophia, EML, solid plates or mesh plates, etc

There is the hybrid Tom Evans Linear A or B which is a powerful SET......<<

Incorrect.

Neither amp is a true SET.

Chadeffect,
By definition an SET uses one output tube i.e. 2A3, 45, 50, 300B, etc. per channel.

The Linear A is a single ended, Class A, ultralinear stereo amp. It employs 4 tubes per channel.

Perhaps you misunderstood what Tom was saying.

Chadeffect,
I think you've characterized the 300B accurately. It's a wonderful tube if mid-range and warmth is your deal.

Personally, and provided the speaker is amplifier friendly, I prefer the 45, 50, PX-25, and 2A3 in that order.

YMMV

From Wikipedia:
>>A single-ended triode (SET) vacuum tube electronic amplifier uses a single triode to produce an output...............<<

The same or similiar definition can be found in a number of other reference documents.

A parallel output triode amp using single-ended topology is abbreviated as PSET; it is not a true SET

I hope that helps.
