Hi,
Stay tuned , coming soon the revolution in an analog amplifier .
Some fundamental differences with the existing amplifiers today.
------------------
No simulator :
Totally independent from the psu . ( Dc power , from + / - 30V to 400V ) (in agreement only to power devices).
Dissipation independent of the rail voltage.(@ idle as bias)
Power dissipation ( from the input stage to the gate of the mosfet ) = 500mW .
BW Power (input to gate mosfet ) = 150Mhz .
Power BW ( @ output) = 10Mhz
Output Offset = 300uV ( under any circumstances )
SN / R = not measurable .
THD + N = not measurable in the range of 30W output.
total efficiency = 72 % @ 4R
Balanced input 2x600R
-------------------------------------
I did not start my life on the class AB , I have designed 3-4 amps , one is the HB- 300 . I applied others knowledge without a doubt.
For some time I had in mind to eliminate the classic circuit used in amplifiers , I see it as a "ball and chain" , unnecessary absorption , which increases when we want to get speed (for transients audio).
a lot of bjt , with the problems that we know. (I am referring to amps full)
None of this , we got an amp that seems designed by transients. 🙂
...."You can for change"
Regards

Eheheh! the world wait this 🙂 ...for logic reason i mean.
thanks for your interest.
I can not display the prototype, so expect (7-10days) the arrival of the ready modules.
The first two versions (heatsink included .. very incredible size) for 400w rms (3R) and 800w rms (3R).
Obvius i partecipate the new concept used with good explanation, diagram etc.
Hi,
No, it was due to pure class A (to the point of work that uses, as well the input signal process also).
We have request for assessment of the working class (for release new class), but frankly, we have little hope that they are at the head of .. rebus.
I prefer the name that was given. "VXA-xx" 🙂
Uhm.. somewhat agree on this. but my work is completed at the time that I put into production a product for third parties.
I do not think that "helps" or "does not help" when you have in hand, a real new architecture. if you look at any amp, the "engine" is always the same as the "engine" of the car, it makes no sense that developments in control electronics.
are the pistons that you should remove!

Yes, absolutely ...🙂 the problem is to hide the truth ... 😉 ... i'm not ready for a mass production ... many prototypes still working anyway ...

This is like saying I have a $1,000,000 prize... but I'm not going to tell you how to win it. 🙄

If I did have something , I would show it after announcing it.
I would expect any "real" revolution from the likes of Cordell /Pass /Self
or other top amplifier scientists.

This is also a good experiment for human. without scheme and explanation...brain already worked...how is possible i have obtained this.
eheh!
but...sorry and with respect, what have developed the lord of amplifier in this 20 years? a buffer input? (that is not already known i mean) and continue use of mosfet..as bjt?? well...this is incredible!!
-------------------
No prolem , my architecture has solid explanations , and scientific knowledge, the problem is that there is little to explain, almost humiliating ease (I mean in the path of the signal) , of course there is some complexity in the circuits that allow the operation .
for the " revolution " is a revolution ! no bjt , no connections with the rail vcc , these two are all to imagine that the scheme has nothing to do with all amplifiers.
wait the modules please.
