Just dusted off my K8000 board, I made it a few years ago and never got it working, not even plugged into my PC.
On taking a closer inspection i had realised that i had plugged in IC24 (6N136) upside-down. I reorientated this plugged to the mains and now I now measure between 15v and 22v from the 5v test pin.
Does anyone have any idea what i have done horribly wrong?
Thanks
Roy
