please check schematics before layout.

Still some 3D components missing...

Ok, go for Vlad...

Wima FKP2 is ok for C2 and C3. I think about Mica because guys from here seem prefer this kind of cap on those place.

Here is my check on the schematic:

- R9, R25 could be CMF55 type.
- T1 = T4 = T6 = 2N5401 need C & E pin swap.
- C5 is 5u6
- Please add 10K resitor // with C26 and C27

I made a mistake. 10K must // with -38 | GND and -32 | GND. Type = BC PR02

How do we proceed?

I can give you the EAGLE binaries?

You downlaod the EAGLE 30 days free demo version; you arrange names and silkscreen informations; do post-processing and order your PCB.

Jean-Paul

Hi,

I think EAGLE binaries will be just fine. I can arrange the files and send it to a local PCB company here with no prob, I already have some exp with EAGLE software. I already ordered the parts needed for this project, will post results when I completed it.
 
Hello Vlad,

what do you mean?

Jean-Paul

Hi Jean-Paul,

It looks good to me. You are a genius in PCB design!
I don't have any photos of the completed amplifier other than the link with the assembled PCB from the page I sent earlier:

http://www.zen22142.zen.co.uk/Circuits/Audio/gempcb.jpg

Just to check - I measured the .png board to be 105mm x 175mm - is yours the same size? Also, will it have silkscreen with components on top?

Thank you very much,
Vlad
 
Hello Tom,

... see attachment!

I´m using a lot of layout tools in my job (ZUKEN, EAGLE, ALTIUM) and today I can confirm that EAGLE is be able to handle complex jobs (my last job with EAGLE was a custom 5th generation i7 motherboard with active cooling in a 5,25 inch case for military flight usage).

Regards,
Jean-Paul
