Hi elviukai,
the Aleph3 and the ZENV4 would be an option.
Both single-ended class a and around 30W.
The Zen´s you´ll find here ; just click on amps.
For a good understanding download all pdf-files concerning the Zen even if you "only" build the ZenV4.
For the Aleph3 you´ll find the service manual here .
Do a search in these forums. You´ll find endless threads about them.

Regards
Jens

well 120 000uf.. 🙂

yes I saw theese too. but how I buy lets say 63V 10 000uF more or less good caps(philips bd series) it will be about 200eur, to caps only, otherwise its a good project. using the cheapiest caps, wilo not be point to build single ended class. what about jlh updatet a class amp?

A lot of people built the ZenV4 with just the capacitance recommended in the article so around 25000uF.
Looking at the prices you get you´d need at least 4 caps for stereo.
Building the Aleph3, the service manual shows 8*22000uF per channel (voltage rating let´s say 35V).
I´d say you could do with much less regarding the ZenV4 is very similar in power draw from the supply and other details.

I´d give it a try.

There's also a 20Watt real SE class A project from Rod Eliot. It's a variation of the Project 03 amplifier. From the looks of it, it should be a difficult amplifier to build.
