Thumbs up DIY HiFi Amplifiers in Ceské Republiky CZE

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!

Default 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)

Smile Hope PMA (Pavel Macura) comes by later

godfather_cz

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 pĺ 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.
