Stanley Meyer 8Xa Circuit

Stanley Meyer 8Xa circuit. Actual Board may differ from picture


The 8Xa circuit is assembled and ready to be connected to the other components.




  1. Cuts power down to 2 amps or less

  2. Your generator runs cool - no overheating issues

  3. No mixing harsh electrolytes like lye

  4. Much safer for both you and your engine

  5. Less maintenance - just add tap water or well water

The only additional components you would need for this circuit is a Variac ( 0v - 110v) if you are not hooking up directly to your alternator. The kit includes the following: 100 ohm 10W resistor, SCR (C38M), Full-wave Bridge Rectifier, and a couple of VIC coils (18ga copper wire with around 60 bifilar turns on ferrite cores).

Finally,  the Stanley Meyer circuit that you need for high HHO production at low amps using just tap water. $320.00 shipping is free! Please allow up to 4 weeks for delivery.
