need some idea about Class A amp

[space2000]

Hi all,

I just want to try to build as to have some idea for pure class-A amp before I make “Aleph-X 100w”.

Pls post me a pure simple Class A amp by using Anyone of this output transistor 2N3055 , 2sc5200, 2sc2922 or 2sk1058.

Thank you for your kindness.

Best regards
michael

Have look at this website.

ZenQuito is an interesting Amplifier
Preferably biased into Class A.
There are several variants, and in my opinion, they are Good Amps.

You will find several good topics. diyAudio members that have built ZenQuito, like:

True.
Also notice that Mr. Plantefeve amps
have current feedback instead voltage feedback.
Both Zenquito and Buzquito (or Mosquito) can be biased to class A or AB.

ZenQuito .. at diyAudio.com

You should also check out the:
Hiraga Class A amplifier - The Monster (Le Monstre).
It is a classic and very well known amplifier
designed by a famous amplifier man: Jean Hiraga of France

Wasn't long ago we had a topic about this Great Amplifier.
I posted some myself:

This is a very good page on amplifiers. If you have a stereo bought from say, Walmart lying around, you might be able to use this page to 'step it up' and make it sound reaaaaaally good.

The schematic at the bottom is a class-AB design, but higher up he uses a class-A output stage.
