Some limited, non-technical (and possibly incorrect) observations regarding push-pull vs. SET: Push-pull: cheaper in general and per wattage output; more tube options and therefore more "tube rolling" possibilities; more amp options to choose from generally; usually more powerful and therefore able to drive a greater variety of speakers.
A single-ended "class-A" amplifier is less effective than a push-pull amplifier. The output power that can be generated improves the power that is available for a given supply voltage and is more than the continuous consumption rating of either transistor or tube used alone.
The two main types of output stages for guitar amp use are single-ended and push-pull. These terms refer to the amplifier output stage circuit "topology", which is the way in which the components in the output stage are connected.

For a balanced amplifier, would the best design for Class A operation be two single-ended circuits, one for the in-phase full cycle and the other for the inverted-phase full cycle, so that all transistors are on all the time? No crossover distortion, no dead time that you get with push-pull.
Each of these three amplifier properties can be implemented independently: An amp can have unbalanced (single-ended, common ground) input with "balanced" push-pull amplification and supply balanced or single-ended output. Some amps have balanced input with single-ended amplification with internal common ground but supply balanced output.
Soundwise is single ended better than push pull? Can push pull designs be made to conserve even order harmonics?
Single-ended amplifiers are generally simpler and more economical to manufacture than push-pull amplifiers. They also produce a warmer, more analog sound than push-pull amplifiers.
push pull or single ended First post here and appreciate any replies. While not new to high end audio, I've never had a tube amp. Looking to purchase a new amp for my mid/tweeter cabinets in a bi-amped system. Thinking about a tube amp as I've never had one and have read a lot about them, mostly all positive.
The power amplifiers are build so, that the first stage provides all necessary voltage gain ( in you example pre-amp stage) to get desirable voltage to drive the output stage (push-pull amplifier)
