Are those pics of Rudi uploaded or is it an image shack?

Patrick,

I use "www.directupload.net" to store my pictures and insert a link to the URL, that is reported back to me, in my post.

Currently I do not see my pictures as well.
Maybe the "directupload.net" server is down.

Best regards - Rudi_Ratlos

don't use your "store" to link to DIYaudio pics.
Attach your pics to your post.

Dear DX Blame friends,

from the answers, I received from you, I know, that most of you will either build the DX BlameES or the DX BlameST.

Very few of you plan to build the MKII or the SuperCharged Version of the DX Blame.

Therefore I decided to offer you the PCB version, that will accept ALU L-brackets.
MeTal and I are just finishing the silkscreen of this PCB.

I think (bet), Ryan, that an ALU L-profile (depending on the pureness of the aluminium being used, if you have the chance, take a copper profile)
will dissipate the heat sufficiently, even for the DX Blame MKII version.

In case of the SuperCharged version of the DX Blame I agree with Carlos, that it would be better to directly mount the power transistors to your heatsink.

For those of you, who plan to build the SuperCharged version of the DX Blame, I have included the needed Gerber files in this post.



As I told you, I will order the ALU - L profile PCBs on weekend, March 26th.
Be sure, that you will get best quality, red-and gold (sorry, CafeChaud) PCBs, that you have ever held in your hands.

Best regards - Rudi_Ratlos

P.S. @Goldkenn: You do not need to order PSU PCBs; the PSU is part of the PCB.

Forum folks can enjoy that...but pirates will copy and you will have your lovely board design, very soon, beeing sold in Ebay, and half your price and having parts included...they can do that.... in special in China as labout costs are low, and production is high..so..part's cost is low too.

I have asked you not to do, but i do thing you was faster publishing and have not readed my appeal.

Well.....to me what matter is to have my circuit world wide...this will help, as some pirates (mainly from China but not always from there) may copy and will spread it wide world the way i want..so... at the end will make what i want.

There's a lot of offers of Jan Dupont and Dx Amplifier boards in E bay...very cheap...sometimes 50 dollares with all parts included in the package..i could see a stereo board, with parts included by 50 USD....and they can do that even cheaper.

I will not provide blue board gerbers opened to the forum to avoid this...only forum management will have them..so.... at Ebay, in the future, only yours.

regards,

Carlos

Hi Rudi,
I am likely to go for the Supercharged Mk II with this board. I will find a way to get the heat out of the devices .

One thing to check if possible please. I have some On-Semi MJL output devices. When building the ST ('stock version'), I tried to use these devices but unfortunately, the leg diameter of the On-Semi devices did not fit through the red-board holes. So I reverted to the toshiba output devices. Is it possible to make the holes for the output devices just a bit bigger?

Cheers,
Ryan

Thank you for your comment, Ryan.

I took a look at the datasheet of the MJL transistors.
The diameter of the transistor's legs varies from 0.93mm to 1.48mm.

The drill diameter of the TO-264 package in the corresponding EAGLE package is 55mil (corresponding to 1.43mm).
I will change the drill size to 59mil in my current layout.

Ryan: it does no harm at all to the PCB, if you enlarge the holes for the power transistors with a 1.5mm drill manually.

Best regards - Rudi_Ratlos
