Default TDA1541/SAA7220 replacement board

For those of you who hate these as much as me, this is the thing for you. Turn your old 16-bit, 4X CD player into a 24-bit, 8X hotrod.

For those of you who still like them, ignore this post. And no more hate mail. [joke]

This board uses a DF1704, and 2 PCM1704s, and a reclocking circuit. It accepts I2S.

You need to supply +12 V for the digital, +/- 22 V (or so) for the analog, and your own I/V stage. Connect BCLK, L/RCLK, DATA, and SYSCLK, along with mute and de-emphasis controls via 10 pin header.

Anyone interested can e-mail me for details.

Hard to believe it made it so soon. Any problems with customs?

Nice use of ground fill on the topside. Think I'll copy that, if you don't mind. ;)

I'm going to be in your part of the world sometime in the next month or so. E-mail me, and we can go stuff our faces at Vincent's or Mineo's. Assuming they are both still there.

Jocko makes 'em. So he's the sole source. It's a beautiful thing.

Default Dac

Hi!
Have populated the board
-and sold the CD player it was intended for ,

so a standalone DAC kit will be more interesting.

What about that I/V stage and reciever?
Are they ready to ship, or just on your drawing-board?

I have some of the old I/V stages left. Thought I told you about them.

The new I/V stage is just an idea. The Rx board is something I am in the process of starting to think about making.

Default Got my Jocko boards.

Just received one of Jocko's PCB and I/V board.

Let's see if the attached photo of the I/V board comes through.
