I have five pcbs (unpopulated) left of the 10 I had made a couple of months ago.
It is designed for use with Ian Canada's I2S to PCM board so one dac receives +/- data for 1 channel, and both receive the same bck and LE.
The left hand dac on the board has a jumper which enables it's mode to be changed from simultaneous to two's complement (I2S) so it can operate alone as a stereo dac. (pin 3 is the data input, pin 4 is not connected)
It would be possible to run them in parallel by reconnecting pin 27 of the right hand dac to +5v.
I am selling them at cost price + shipping for anyone who wants to experiment with single or dual balanced / parallel operation and with EC Designs low frequency dem clocking.
Because the dem frequency is so low, there was no need to use smd components, or mount them as close as possible to the dac (in my opinion).
With pin 16 of both dacs linked and dem clock of around 50Hz, the 1541's have never sounded as good.
There isn't a BOM nor a schematic (straight from brain to layout - hence the missing track!)
Please pm me if interested.

All are now sold. Thank you.
If there is a demand, I will have more made and of course, with the missing track added, and possibly with any other minor changes requested.
Cost will be around £5 + shipping each.

Okay, if I have any more interest I will open a thread in the group buys forum.
Thanks.
