Based on the schematic, pin 8 on both DIPs should be 9vdc, pin 4 0v. All the other pins on both DIPs should be around 4.5vdc. If you do the Facemelter mod and switch it on, pins 1, 2, and 3 on IC2 will drop to about 2.8vdc.

Hi!!
sorry for the necro-thread...

Did you manage to find what was wrong with your build?

Mine, I had the same problem. then I am trying the jaymaze mod, but now I can't get any sound out of it: I mean NONE!

I checked for bridges, shorts, IC voltages... everything is OK.
The bypass is Ok too.

I am lost here...

Help?
