Diy Dac

[steve]

Finished this a couple of months ago. It's built on an old WAD 6550 chassis. The designs are at:

and a kit of the hard to get parts like the PCM, VCXO and the digital PCB are available from:

http://www.tentlabs.com/Products/Com...DAC/index.html

I had to design and etch my own double sided output board to fit the valves into the 6550 chassis but everything worked first time and it sounds fab. I had been using a Rega Jupiter but the external DAC is a definite improvement. Everything much clearer and the music rocks. I can recommend this to anyone although I have not been able to compare it to any other designs yet. I estimate it cost me about £400 including valves with the custom HT TX being the most expensive item with the Audio note caps and tant resistors coming in a close second. The components from Tent labs were very reasonable £160.

Switch to Thread mode to read the info on the plans for this design.

thread mode? I'm a simple soul.

I lke the look of the huge chassis with only a couple of valves sticking out of it.

does 'thread mode' tell us more?

Hi Andrew,

Up on the right, a dropdown selection called Display Mode. Set it for "Switch to Threaded Mode" and you'll see more info. Don't ask me why!

Cheers,
Tony

thanks Tony

Thats a great effort, looks like you used the same Crystal reciever chip that I bought and then fried along with 4 of my 8 1542 DAC chips when I made a PSU polarity balls up!

I got as far as buying a new Crystal chip and designing a PCB as I free formed the last one on proto board.

Looking at the pics might motivate me to do something with that rack mount box full of stuff I aquired for my dac.
