zen headamp info,you can download my protel99se ddb file.

The boards size is 91X64(mm).The price is $4 USD per board.One amp need two piece of PCB. Use CHINA POST(ship) costs is $5 USD.

you need to email me directly to place an order. Instructions on this will be posted to this thread.

Boards, Total = 30 pieces.

One AMP boards,PART LIST:

R5\R6=220 ohm,1/4W
R10\R11\R12=2.2 ohm,1W
R15=470 ohm,1/4W
R18=5.6 ohm ,3W

trim R16=100K,R17=1K

C4\C5=1000uf/63v ,ELNA FOR AUDIO
C6=2200uf/50v, ELNA Standard Audio Grade

connecter, 2 pin(3 pieces)

I can offer the resistance and capacity KIT package.Including all resistance and capacity the board need.The total cost $18,shiping by CHINA POST.

So how much for the board and components? 22$?


digi01 9th March 2004 04:36 AM

yes,the board and components is $22 USD.Make a stereo headamp,you need two sets of these.

NOTICE: the components is not include the transistor Q1/Q2/Q3.

OHH,I have written a should be the 'resistors' :dead:

There are two kinds of resistors.the small 1/4W resistors is standard metal film,the big resistors R10\R11\R12 and R18 are DALE type.

If some of your components are bigger there is enough room for modifications.
This is a experimental version,I use some different components inside.

All the project's details and PCB layouts of the original version can be found in the Headwize site:

Hi Marcello,Thanks for a very fine contribution.ZEN headamp is my first project of your design.Do you hope that zen is as one kit? I wish this amp can be more diyers make,just like PPA ,gilmore and such these.I do not have experience in this action, your view?


tortello 14th March 2004 05:50 AM

Hello digi01, for me there is no problem at all.
If somebody will ask me again the project's PCBs, I will redirect them to this page.

I am interested :smash: :hot:

Anyone else from Germany interested?
