"any of you guys do a A/B - same system both amp types ?"
Not only same system but same driver.
Circlotron output stage using 4 6as7g's (8 triodes) into a transformer loading the stage at 325 ohms sounds much better than 8 6as7g's (16 triodes) driving 8 ohms (OTL).
It's much more linear, less HD.
Neither sound as good as the SET. The 6as7g is just not all that linear no matter how you load it.
I don't think any of the super low plate resistance tubes (made for pass tubes in series voltage regulator circuits) are.
