@mozartfan Man, you're all over the place, too many bold pronouncements about this or that being best. I love SET, and have two actual SET amps and one pp. Own or have owned two 845, one 300B, one 2a3 for SET. For pp, EL34, 6550, KT88, KT120, 6CA7. To say any of these tubes or amp topology is best simply untrue. I've enjoyed both pp and SET and all these tubes at one time or another.
I'm Verstappen and Red Bull fan, not into Hamilton or MB, but I'd have to say Hamilton and MB got ripped. Hamilton increasing his lead with worn out hard compound tires, he was cream of crop that day. What officials did was NASCAR shenanigans, fake competition.
