"You do understand that that is just a term that DF made up, right?"
DF builds the most powerful 1W SE 2A3 amplifier in the history of audio.
How did he do it?
Transfer efficiency per DF's application is a key concept.
Learning from a "master builder" is never a bad thing.

You gotta understand! These folks don't want concepts-- NEVER!What they want is facts & figures that they can download
from the Internet, and "prove" something.It's a result of Television-- don't think for yourself, let
the T.V. or the Internet "prove" it!.Then, you have it made! You're RIGHT even if you're WRONG!
This era of illusions is getting long in the tooth now.
PERFORMANCE will have to take it's place. Ask any Canadian Trucker!-Dennis-

Dennis builds a 3W amplifier. ;)
According to Dennis his direct coupled 2a3 amplifiers are rated at 1 watt and should not be operated at a power level beyond that.

You can run it wherever you want, you can't
hurt it- it's pretty Bulletproof.
For best sound, you run it where the heavy-duty
power supply controls the dynamics, not the output watts.
At the very best, what this requires is a speaker that
has full dynamics at a watt or less. If it can't fully
fill a large room at loud levels and maintain full
bandwidth and dynamics, then you have the wrong speaker.

Wattage is a measurement of power. Therefore if an amplifier measures a watt, then it's a watt. How can a watt be anymore powerful then it measures?

That would be continuous power-rated where
a watt is indeed a watt.
Speakers, however, don't operate on continuous
watts, they run on impulse peaks.
If you want to fully experience that, then the
amplifier power supply must be ultra-fast-- with
minimal recharge time and density, and minimal
storage of energy. Both contribute to clean
dynamics that are fully in-tune with music.

"How can a watt be anymore powerful then it measures?"
How can a 1W SE 2A3 sound "subjectively" more powerful than a 400W solid state amplifier?
DF has be discussing this thing called "transfer efficiency" for years.

Oh my...
I can put a Watt into the air. There is no way one of these fantasy amps that puts 1 Watt into the voice coil terminals is going to deliver that.
I assume at some point you will discover you have been led around by the nose. Probably not today, or even tomorrow, but at some point you will.
cheers,

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
Maybe its a watt at 20hz???
A watt at 1Khz most likely won't produce a watt at 20hz on a tube amp.

"DF has be discussing this thing called "transfer efficiency" for years."
And you believe him?
That makes you look a little kooky.

Cheap console stereo rated at 600 watts IPP per channel.
Instantaneous Peak Power!
I think you mean that DF made up that terminology years ago and hasn't stopped trying to get people to believe it.
In London on Tottenham Court Rd in The '70's as a teenager I would druel over the amaising statistics of the amplifiers. Took me many years to realise it was all lies! Some people havent learned that to this day.
And where have you been for the last 5 years Mr Barker? I recalled reading some of your posts from long ago and had to check your history.
The trials of life friend.
I must say its a filip to my state of mind to see so many of the old names still holding up the banner and giving great advise as they always did. Wont name them but really feels like home from home. I came in here because the majority people in UK I mix with in these matters are so far away from from my ways that have never changed from my beginnings that noone replies to my posts. There has been a massive dropoff in practical knowledge, or interest in the things still being discussed here. I even fear now for the forthcoming loss of value in vintage valves as the old guys drop off their purches, the youngsters are building class D amps, and our stocks of valves chokes and transformers will be loaded into skips after our funerals. But the main issue is nobody wants to bounce ideas together with me. It was like home from home just checking in here for ages.
Count one more person super-happy to see that name posting. May all the trials be in the rear-view mirror!
