---lineup--- for your schematic ( can you make better quality = bigger Image, please )
Interesting!
Big èçáðàæåíèå, the output is taken from power technics. Where speed of management of the Output!!!! Specially the bottom transistors of the bridge are not braked.
The scheme-FAB-repeats ñçåìó Nad320 which is repeated in turn with " Parallel amplifier Ageeva "
p.s. Excuse for my English, he/she is the electronic translator

Hello, friend vAD
How is things in St Petersburg ( ex. leningrad )
... not very far - go boat Across Bothnic Sea ..come to my land, in north


What is wrong? With image?

I put link in POST UP here in topic,
to my schematic www.diyaudio.com attachmentment.
AGAIN,
This link to my SCHEMA:
http://www.diyaudio.com/forums/attachment.php?s=&postid=1130867&stamp=1171019146

I think it is very Good Picture = Perfect Information! :)

I have my Original simulation circuit still in SIM
and I can make some new image from this.
But think no need ...
What is problem? I do not know ....

Very Much Thank You
......for interest in
Lineup Audio LAB
Diamond Class A Power Output - JFET Input
........ and many other amplifier projects

Big ??????????,

Specially the bottom transistors of the bridge are not braked.
The scheme-FAB-repeats ????? Nad320
which is repeated in turn with " Parallel amplifier Ageeva "

-> he/she is the electronic translator
no problem - I get your talk, most of it

See schematics in my attachment here:
your posted schmeatic 'hawksford'

I like this one: This IDEA is good and very fine!


Fast Small signals, with 'better parameter data',
than slower Power Transistors, full of capacitance Cin , Cout and whatever.
- Driving a paralleled pair of Output 2SK1058 / 2SJ162
These Lateral MOSFETs are among
the most easiest-to-drive Output transistors we can find.
In all categories: MOSFET, HEXFET or BIPOLAR !
Besides these are pretty linear in operation.
And have lower voltage Gate-Source, Vgs.


So, the idea is perfect!
Get pre amplifiier qualities into a Power Amp.
------------------------------------------

Some details should be sorted out and fixed, to get this working.

MJE350/MJE340, are excellent for Cascoding BC550C BC560C
and similar great low noise TO-92.
Like done in VAS.

A little question mark, for the output drivers:
Q14 and Q16, can those BC557 - BC547 really do an optimal job?


The idea of more Local Feedback, instead of Global,
is also in my taste.
Remains to see how well it works with FB taken from
in between those diodes in Vbe multiplier.
-------------------------------------------------------------


VAD
I want some more ideas from you :cool:
Hope you will be around here again soon.

I understand you prefer to communicate in Russian Forum
in your native language.
makes so muych easier, to say what you WANT to say.
What is in your audio heart.

Regards
lineup
