[digi01]

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.

R1\R2\R3\R8=1K,1/4W
R5\R6=220 ohm,1/4W
R7=33K,1/4W
R9=220K*,1/4W
R10\R11\R12=2.2 ohm,1W
R13=100K*,1/4W
R14=180K*,1/4W
R15=470 ohm,1/4W
R18=5.6 ohm ,3W

trim R16=100K,R17=1K

C1\C3=100uf/35V,ELNA CERAFINE
C2=4.7uf/63V,ERO
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.

Q1\Q2=IRF610,
Q3=2sc1815

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

Thanks

 

[digi01]

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.

 

[bzo]

what kind of resistors are they?

 

[digi01]

OHH,I have written a mistake.it should be the 'resistors'

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.

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?

Regards-digi01

 

[tortello]

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.
Cheers
Marcello

 

[roibm]

I am interested

Anyone else from Germany interested?

 

[Lucas_G]

Hi Digi,

I have just emailed you on this address: zanghb@bjtzh.gov.cn

I would like to order 4 boards.

Maybe there are more people interested in the Netherlands?

I hope we can pay you thruogh PAYPAL.
Do you have an account there?

With kindest regards,

Lucas

I am considering purchasing two boards.... but am at school right now and cannot send email. Just wanted to express my interest (though I am not certain whether I can buy or not). Do you have any schematics drawn out to match your board layout? I noticed that the parts names are a little different and was wondering which ones compared to the original ones in the article. Thanks

 

[digi01]

Thank you tortello,thanks all🙂
This is my sch,I use protel's auto-route function, through sch turn into pcb file automatically.according to the actual conditions, I have revised some components(D1/D2 with 1N4148,Q3 with 2sc1815)I
Indeed,you can use my pcb make tortello's original version,do not any revise.

regards,

digi01

 

[Lil_JV]

What software did you use to make the layout? I would like a program that has the feature of putting in the schematic and it automatically makes a layout.

Thanks,

JV.

 

[digi01]

I use protel for that.

In fact, the circuit of AUDIO is very simple, it is not essential to use the large-scale software such as protel.Eagle or expressPCB are good choices.
Just because the pcb factory of Beijing makes PCBs only accept the file of protel form.

Supplement ,one board partlist R4=20K

 

[digi01]

For those who participated in the group order for the mini ZEN headphone amp kits/pcbs.I will send out the last batches of oeders this noon.Any question please have been at mail or in this order threads to get in touch me. Thank the appreciating of everybody.

Anyone get their boards yet?

 

[Lucas_G]

Anyone get their boards yet?

Yes, I got them a couple of days ago.

They took a long time to get here from china, but they arrived in good shape.

Very well made pcb's!

Thanks Digi!

Lucas

 

[digi01]

china post may take 2-6 weeks for goods to arrive,but in extreme cases,2 months.
Lucas_G,wish your MINI zen born soon 😉

kind regards
