You can alter the gain by adjusting the emitter resistors on the differential pair

Thanks Leo. I've made that change.

I had intended to have a few boards made, but the Aussie dollar is in the toilet at the moment so It's quite expensive to have the boards done. I'm looking at other options at the moment.

Here is the final stereo board layout I ended up with. Board size is 50mm x 80mm

Hello FordGTlover.

May I suggest the next website for your pcb ?!
a quick price calculation was about 4 USD a pcb.

http://www.makepcb.com/

have fun ! and remember, i am interested in a board or 2 also

I've just been reading through this thread, and I absolutely love the fact that we have some hardcore knowledgeable electronics engineers on here, gives the DIY section massive credibility (even if I haven't a sodding clue what you're all talking about). :lol:

I didn't expect my thread to be so popular:smoking:

I wouldn't pay too much, this was intended to be cheap;)
Other option is to etch your own board, you could use the layout here on page5 as its single sided http://home.quicknet.nl/qn/prive/ra..../index_en.html

You are an electrical engineer? I am in 1st year in college planning on majoring in either mechanical or electrical... then I can understand more of the complicated things you talk about lol.

I just had a quick look, and it look like a great deal. I'll do a bit more poking around, but I think you may have found me a winner.

I agree. I don't want to pay too much. I have never etched a board, and I suspect others are in the same boat. I wanted to give myself and others the opportunity to get the best out of this little DAC for a reasonable price. The place Naqua linked to looks very cheap. :)

I have been following this thread, and you are doing a great job.
When you are finally finished, let me know how much it all cost. Then I can loan you one of my DAC to compare the two...

Thanks for the words of encouragement, and the kind offer.

Cheers

Rob

On another note, I think I'll resize the board slightly to the same size as the DAC to allow it to be 'stacked' on top.:)
