Sophia 300B vs Jeff Korneff 45 Amp

Bill, a minor point, but it is not true that a SET "by definition uses one output tube per channel". Single-ended-triode: single-ended topology and triode output devices. No assumption is implied on the number of output devices. A parallel output triode amp using single-ended topology is SET. In other words a parallel SET is SET.

A lot will depend on your personal tastes. I currently own 45,2A3,300B and GM70 SET amps and enjoy each with different types of music. There are times I really want the warm, liquid tone of a 300B. Likewise, for large orchestral recordings the GM70 is hard to beat. The 45 is an excellent tube but the others have their magic as well. It would be tough for me to live with one SET across all musical genres.

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.

Others do disagree, and if one looks at the name literally, there is nothing at all that speaks about number of output devices.

Single-ended, and triode. Period.

The thing is many people do not seem to understand what single-ended means - they assume it means "one output device" when, of course, it means nothing of the sort, and has nothing to do with the number of output devices.

I am sure you are aware of that.

Single ended, schmingle ended.

It's all greek to you.
