I recommend you build the Balanced Zen Line Stage.

Hands down one of the best DIY projects i ever built. Very well written and educational.

And it is a very good sounding PRE. A wonderful match for your A30!

Do you know some building guide?
Is Zen better than Aleph p 1.7?

Zen looks simplier to build than 1.7 and this is a good thing for a beginner as me!

Thank you

Your A 30 is not loud enough? If, build its preamp-stage. And use the same psu, it of your A 30.
The zen line balanced sounds more honestly than the 1.7, in my mind,-! It demands more experience with speakers, power amps, sources, room ...-) The 1.7 is the better match with multiways or relative complex power amps or so.
I suggest: reduce to the max: A 30 without a further pre, better louder speakers. Or its pre with the same psu(s,-)!!!

I had both, both are pretty good.
To me it sounds that the Bosoz was a Little bit faster i prefered it at rock.
For vocals guitar or harp i prefered the aleph p.

Zen is simpler to build (top for beginner).
But Aleph P is also worth the more work (with concentration and careful work a beginner could do it too).

where do you get the pcb`s?

Other Pre`s i`ve not tested at the Moment.
A BA3-balanced Looks also relative easy to build.
But how it sounds with a aleph?

And I would not do a B1 its a good pre too, but a think it lacks the drive.
With Bosoz, Aleph P & B1. B1 was on reserve bank the most time.

BA3 Bal , , Frenchie UGS preamp

and , of course , already mentioned , certainly easier to make

NB that foundation of good preamp is good PSU , which is strictly shunt type reg based , if you ask Mighty Moi

(your mileage may and must vary , and that's strictly your problem )

Lots of good suggestions. I've seen recent threads on Aleph p1.7 pcbs so they may
still be available. The original balanced zen line stage PCBs are likely long gone,
but the art work is available in the article so one can always edge from that.

The Balanced Zen Line Stage article is a wonderful read and what you can learn from
it will serve you well, even if you end up building something else.

Cheers,
Dennis

it's fun to make your own PCBs... there's a sense of accomplishment that you don't quite
get from boards you've purchased from a group buy.

go for it, if could do it, you can

Actually the most difficult part of building a Preamp is Volume Control, Input Selection, and building
a chasis with Ins Outs, etc. For your first one just keep it dead simple one In - One Out - a simple volume
control like mentioned in the article. Don't get bogged down in digital volume controls and relay actuated
input selections, etc.

The BOSOZ pcb layout looks cool IMHO

when you compare it to the Aleph 1.7 - it looks like the Lite version
