SET Shootout China VS The USA

@billwojo please don‘t go there. After only brief contact, some poor souls have lost their will to think……..

@atmasphere I take it you have a 12AT7 LTP @ +-300V with something like a cascode 10M45S CCS below? Or are we talking fancy pants?

I don‘t think the technology is an issue given that it is pushing a century……

I’m glad I stocked up on 307A’s when they were relatively inexpensive. It was inevitable that they were going to be ’discovered’’ at some time. When used correctly they sound particularly fine into special edition Magnequest FS-030’s using the 4 ohm tap. The bottom end is quite authoritative for a SET.

BTW the 307 tube is not a DHT but is in a fact a pentode tube.

There are a couple of ways to turn it into a ’virtual triode’ with rather attractive plate curves.the equal of many a ’native’ DHT.. ie when configured in this fashion it can effectively be considered a DHT.

Triode strapped 6AV5 didplay remarkably similar plate curves to the 2A3, but are insirectly heated.

I had no doubt of your motives Charles, just thought an explanation was warranted.

Once you hear what they do there’s no going back. If your SETs don’t use 6SN7s there’s a whole better world out there...

Better still stay away from the N7’s madding crowd and stock up on some 7193’s while they are still affordable. No contest IMHO. Kinda cute too - if you're into Mickey Mouse.....,.

@mozartfan if your tech is real hair shirt get him looking at DHT drivers for you amps.....transformer coupling. Enough to keep the OCD going for decades.....

oh, and what @larryi said too - with the emphasis on typical !
