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.

Sitting here listening to an excellent PP 15 watt 2a3 amp and I say nonsense there will be plenty of PP amps around in 20 years.

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

You are so absolutely full of it. Are you going to say that there is no compression either in those little pieces of crap?,.

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.

Sorry to burst your bubble, but your new Chinese amp is a push-pull amp, not a single ended amp. ~~~~~~~~~~~~~~~~~ You know I was wondering about this.. if it was actually a PP...?? Went and ordered in secret w/o telling my tech, ordered on binge late at night,,, hummm, I thought all SET type tubes were SET amplification. hummm, wait til my tech finds out... **I told you soooo*. His famous line. hummm, well, ,,, hummm. uploading new video on the UX250,, Sophie Milman, bass check, Highs check. No roll offs. Goes to show, what we’ve read about FR from decades of **dis-information** is simply just not true. I was wondering,, dual 2A3’s, and I read on descrip of other amps with dual 300B tubes mention of a PP type design. Lets hope we have the super linear midrange in this amp. Yes it is in fact the Yaquin. New upload soon, what you hear in the video is as close as to being in the room. Not sure why folks can’t hear fidelity in my latest FR speaker uploads, vs the older Seas Thor uploads, which indeed had distortion. The Sony cam picked up the distortions of the Seas Excel drivers. But clearly if you can’t hear pure linear, clean mids in the video,, well then I can’t help you

Just cked

SINGLE ENDED. Not a  PP circuit.
