Pin 34 on U5 held high.
Correct !
Pin 15 U5 held low
Pin 12 Z26 held high
Is the mod in between these 2 pins? they should both be low on the schematic...
AFAIK the mod doesn't touch U5. Pin 13 is the only one which buzzs out to where the mod is.....
Pin 40 on U1, with DMM 0.0 then jumps to around 4.5 to 4.8v and holds there.
