Thanks Matthieu

I just added some more service manuals: Marantz CD6000KI, CD7300 and SA-1.

And now for something different...

DOS PCB anyone??

6h5c · 07:47 PM

Due to multiple requests over the past few weeks, I decided to do a small production run of my DOS PCB. They are not as dirt-cheap as the Flea boards because of the small batch size, but for €14.00 ex. shipping & PayPal, you can be the proud owner of a stereo board!

The PCB holds two identical sections for left and right channel. They can be separated mechanically with a PCB cutter if desired. Ground planes for left and right are also separate, but can be linked by jumpering a number of via's. The circuit is identical to that on my website. The schematic and partslist can also be found there.

If anyone is interested, drop me an e-mail at

dospcb@raylectronics.nl

Regards,

Ray

Ooh, very nice Ray!

Thanks, it looks so much cooler than a home-made PCB, with solder mask and silk screen

I'm thinking about rebuilding the one in my SA8400

Finally this forum accepts larger image sizes

One for me! It's been said the Philips CD950 and its TDA1547 deserve it

No problem, Matthieu. Could you drop me an e-mail, so I can collect all the orders in my DOS-inbox?

Very wise choice Matthieu!

Have you looked at the 1547 datasheet yet? you can bypass the inbuilt opamps and output directly through the DOS. Lee did this on a CD17! You should ask him about it!!!

Another very tidy looking board Ray! How many boards did you have made? i'm wondering about the set up costs for a small PCB. Ian

Yep I've already sent him a PM. Hope the filter parts are the same as I still have many resistors of the right value! And yes pins 10/11 and 23/22 waiting for DOS

Unfortunately the PSU of the DAC is a bit complicated. Let me fix my CD53 to sell it to buy speakers matching this sleeping wonder! (I hope so...).
I will be banned for TDA1547 corrupting the forum...

Ian,

thanks. So the clock just feeds a signal to the DAC. I had thought that a signal would pass through the clock (input and output).

I will get onto this mod this week at work. I may order the opamps and bypass the hdam at the same time while its all open.

Are there other straightforward mods that give good gains?
