Hello!
I followed up some links provided by PMA.
I was gladly surprised by the stuff I found.
Very nice Amplifier Circuits - REAL DIY HIGH END
I hope our Tjeckish members can fill in with more info
about good Audio Schematics in Ceské Republiky.
------------------------------------------------------
Some very good stuff:
RoyalSound - Schematics
Macura AudioPage (PMA at DIYaudio)
Macura has some very low distortion Amplifier Systems.
It is based on local feedback in Voltage Amp
and a Power Buffer.
There are design both MOSFET and BIPOLAR.
Below is just a sample-schematic from Macura AudioPage.
Regards to Czeckia!

dyi in czech repuplic
greetings to everybody from czech repupublic,
(that is proper english name for our little CE state).
i am glad that someone noticed diy activity in our country, especially pavel's work. his a true specialist, as far as i know hi makes his earning by designing industrial measuring systems where low noise amplification is a must. At Rod Elliot's pages can be found also his simple power mosfet follower A amp.
i think, that dyi lives here, but in form of replication, not self design. i've seen many pictures of homebrew alephs, but i sense, that buying an comercial product in studio is more common case. A Pity. A lot of diy is based on IC design and i don't count that.
You can also look at www.hifiart.cz pages, it is commercial but one man show. Look also at czech pages there, they contain more pics.
btw: i enjoyed your misspelling, halojoy but i am aware of my english also But Tjeckish is pretty cool )) (= Czechish)

yes, you are right
I did not use the correct english version
I call Sweden for "Sverige" because that is what we call our country
and we called you Tjockoslovakien, before, when we crushed you in Icehockey (Nedomansky etc)
Nu kallar vi er Tjeckien på svenska.
'now call we you Tjeckien on swedish'
So, I am not English/American, and have no wish to be that
--------------------------------------------------------------------
When i am at diyaudio forum
you might call me "swenglish"
that is the correct way for me to be - whatever ANYBODY might say
------------------------------
halo - the incorrect
"Disney-Anglo-American-McDonalds" -guy
proud to be a from Kingdom Of Sweden, much better!!
RoyalAudio - who is the Royalty of Tjeckien??
Who is your King?

Thanks halojoy for more good links.
You deserve a title for hunting cool websites.
First schematic looks like a headphone amplifier.
I once build something similar and it works really well.
Only the parts are a little expensive.
Especially the BUF634 is a nice buffer for audio use.
On the last picture you sent there is a BUF634 in TO220 case.
I think it´s used for the output stage but can also serve well as a railsplitter where it´s needed. The TO220-version can output 250mA.

The site looks cool. Pity the designs take so long to download!

Thanks, halojoy
In fact my page with low-distortion amps has a following address: http://www.pha.inecnet.cz/macura/audiopage.html

BUF634T
This is really a remarkable circuit. Please have a look at http://www.pha.inecnet.cz/macura/buffer_en.html
I can guarantee that in case you build that circuit and insert it into your CD player you will get 2 class higher - no kidding. And do not forget the R12 resistor (current load).

Re: dyi in czech repuplic
Incredible craftsmanship !!! I have always had a gut feeling that there must be some skilled metalworkers left in countries that were behind Iron Curtains previously.
Here is some DIY attempts of Estonians (well, almost – because those things are now for sell though in local hi-fi store).
http://www.hifi.ee/html/1eesti.html
halo,
Yes Estonia is Estland for Swedish , like Swerige is Rootsi, Norway is Norra, Denmark is Taani, Finland is Soome , Poland is Poola, Germany is Saksamaa and Russia is Venemaa for Estonian.

PMA said:Hi argo,
It is very nice that halojoy has started this thread just to show that there is an interesting hifi stuff in other countries, too
Pavel
It was quite some time since I last "visited" Ceské Republiky.
Any new good Audio stuff?
In Czeckia or in other former yugoslavian land.
New links or amplifier projects?
Pavel, PMA, godfather_cz, Koy or anybody ......
Serbian Pedja is already linked to at my homepage.
You do not answer my questions,PMA said:Halojoy - you are a funny guy
Czech Republic (you say "Czechia") is not a part of former Yugoslavia, but Czechoslovakia. Sweden is probably not the same as Norway, Finland or Denmark. Or is it ??
but thanks for reminding me of my "fault in thoughts"
There is always "sidelines" to follow
if we want to avoid to get into contact
with the REAL question:
What are we living for ...
halojoy from china, mongilia or norway - pick your choice
- I have always been a traveller in my mind -
/quote from a song
or
I have been a rover
I have walked alone
Hiked a hundred highways
Never found a home
Still and all I'm happy
The reason is, you see
Once in awhile along the way
Love's been good to me
