SET Shootout China VS The USA

2A3 SET from china arrives any day now.

The tech who loaned me his UX250 (aka 50 Tube) amp, with a  12AU7 in front + a  6BH7 (??) , has incredible pure Cobalt out trans. ($1k+ each back in 2000, now no longer in production). . he will help me set up the  2A3. 

Has a  AX+AU my 2 fav front tubes anda   quad of 2A3's. 

My speakers are pure neutrality, no coloration, no distortion,. 

So whatever amp/ source you plug in, will register the nuances inherent in the circuit.

Will be very interesting. 

USA has pure cobalt out trans which gives the edge in power, but the china 2A3 has a 2 tubes per channel.

Gonna be interesting and will post a  YT upload with comments,

AFTER TESTING IS COMPLETEED.

Hand on to your horses at the OK Corral. 

Grab a  beer at the saloon, 

sundown shootout at the edge of town.

Does the 2A3 amp have 2 output tubes (2A3) per channel?

Sorry to burst your bubble, but your new Chinese amp is a push-pull amp, not a single ended amp.

What is a set tube amp?

Image result for set tube amp

A single-ended triode (SET) is a vacuum tube electronic amplifier that uses a single triode to produce an output, in contrast to a push-pull amplifier which uses a pair of devices with antiphase inputs to generate an output with the wanted signals added and the distortion components subtracted.

@mozartfan  Enjoy it regardless. As you've seen from other replies, plenty of folks enjoying the PP tube amps.

 What they should have done, to be fair to all the drivers, and to conclude the race with a lot of green flag racing to the end, is red flag the race and let everyone pit and get fresh tires.  Hamilton would have been in the lead, as he should be, and Verstappen, if he stayed close enough, would have DRS after two laps would have been able to attempt a pass.  I think Masi botched the call by not doing this.

What he said...
