281 Interboard Power

Again, A board is top board, B is bottom....

281 PEAK circuit board wiring diagram

Interboard wiring part 1 for Topps 281 clone. Click on pic for large one. This is the PEAK circuit, I built it on the A board, so I omitted the bits shown in red on board B (the bottom board) I also put all inputs to the PEAK circuit through pots, but you can ignore this if you like... All diodes are 1N4148... Where it says "All these PEAK inputs meet here..." it refers to the dot to the left of the text where the blue lines meet...

You can ignore the pots if you wish, but not the diodes...
