DI box(H&K Red Box Mark II)


Build the Hughes and Kettner Red Box Mk II DI box with cabinet simulation. Layout is of course verified. I used this little box for my PC recording stuff. Schematic is at this site http://analogguru.an.ohost.de/ Please note that in the schematic there is no option for phantom powering. It would be better if a bipolar capacitor(1uF) at the output will be used. The 10ohms and 100n in the GND LIFT portion is not included in the schematic. The idea was taken from Rod Elliot(Elliot Sound Products), it can be omitted if desired. Here's the layout:

    This is my first build and I was wondering what the scale should be for the laser transfer method. I have the TL064CN opamp but the lead spacing is not even close to lining up with the solder pads. Any help would be much appreciated.
    Thanks

    Sorry for the inconvenience buddy. The old file that I had has been destroyed. I will try to redraw another and upload a ready to transfer layout later.
