More hints on building 2

OK Some more pics 

The first pic  is the 47K resistor from R55 to ground for the 0-5Volt mod,  in this case I used the chassis pin of VR5, Todd used the ground pin on Q2 but I have an aversion to heating up transistors any more than necessary so I felt the Chassis pin was safer, YMMV

The second pic is MIDI fix using a 2.7 K resistor from pin 5 to pin 7 on the 6N138 opto isolator , pretty simple actually, watch out for solder bridges, its a bit tight there,  and probably a better idea to do this BEFORE you do the ribbon cable 


  • MIDI fix?   What was the issue with MIDI?  Or did I miss it from another post?
