tripath topology amplifier=SET?


I'm hoping someone can answer this: Is a "tripath topology amplifier" the same as an SET? If not, then what exactly is it, and who makes them?

Thanks,
Alex

Tripath is a variation on class D amplifier where name comes from Tripath Amplifier Technologies (that went bankrupt few years ago).

SET = Single-Ended Triode amplifier a tube amplifier with only one (in opposition to push-pull) output tube operating in triode mode.
