    Cool Audio DAC correction amp

    While waiting for a reply or some aknowledgement of my LSX order I got bored and drew up a PCB for an 8 channel full differential correction amp for an audio DAC.
    It also has three adjustable, open collector schmitt triggers on board as the laser projector I bought is only TTL and I wanted a well defined output.
    Power supply can be either a small 7.5/0/7.5 transformer as I am using it or -12V / 0V / +12V dc supply.
    All differential outputs have independant adjustable gain so you can configure each for either 10V p-p for X,Y or user defined inputs, or 5V p-p for R/G/B inputs etc.

    I am thinking of getting some made up. Anyone interested in buying a board if I get a few prototypes produced ? Postage would be from Australia tho' .....
