Silent:arts,

We must clear this up, because it´s still confusion of language between you and me.

You shall absolute not feel offended, (beleidigt) because when you first wrote "just release the PCB" I think you mean that you have make a bunch of PC-cards, and maybe in consultation with Soeren_DK.
In this case I was currious to know if you have use the last and valid version of all PCB versions we have done.

Then when you wrote "but we just need some updates" I say that it was Soeren_DK that handle all information about the PCB layout.

The reason way I think you talk about the PCB's was that me you and Kubi discuss DI-Box 1975 PCB's for your "51X rack system" when we had a long nice e-mail conversation for some month ago, when you was very kind and send me the Haufe ST8456 transformer as a test sample, so I also could add this to the DI-Box PC-board.

Yes, this was the storry, and I hope we have clear up our small misunderstanding.

Bo, no problem, all cleared up
if I do a 51X version you would be for sure the first who knows and proofs the layout.

Soeren_DK, any update from your side?

hi guys, is possible to self- etch a copper pbc of the "Bo Hansen 1975 DI" with this file  layout http://www.mentol.dk/diy/bohansen/print.pdf Is this 100% functional???

I saw in your  picture (BO) "DI front and card"  that you used  carbon 5% resistors in the DI?? exept the 6K8 1% . Is this better for the classic sound of the 1975 DI???

best regards
Juanjo..

Joanjo,

This PCB print was the version I use as test sample, and it´s ok beside some small error as components that was placed to tight together.

Soeren_DK work just now on the latest and final PCB version.

About the components,
This design is not so choosy regarding resistors or other components, (besides the two 6.8k phantom feed resistors) it is only a simple dual emitter follower, "no gain no pain" so use what you have on the shelf.

best regards!

Bo have corrected the last part of the pcb so I will finish it in the next week and then contact Gustav and make a run.

@Bo

Can I use a Lorlin 2P switch such as this one for the PAD mentioned by Chrispbass?

The files are delivered to Gustav, waiting for an estimated date for the pcb to show up in his thread.

Hi Guys!

Soren and Bo,

Please, is possible to post here the PCB Silk (final version) and the Self-Etch Files of the final PCB copper layout? ;D

Again, thanks a lot  for this thread.

best regards,

such good news!  i think i may have just squealed like a little girl, looks like i'll be modding some stage boxes soon.  prost to all for the time and effort!

I Soren,

could you go through the updates to this latest design? I had home-etched the design you've posted here. Is there a lot of difference between them?

cheers

 

[Soeren_DK]

Hi nhaudio.
Great to hear you have completed the etching with luck. 
The only difference from the latest design is the placement of the components. The schematic is unchanged.

Cheers
Soren

Update
In a couple of weeks the boards will be ready if there is no problems with the Gerber files.
