The new circuit includes three functions: Bob Beck, Hulda’s Blood Electrifcation, ionic colloidal silver, and Zapper.

Circuit board size: 68mm*50mm
Power supply: 9V-12VDC
Blood Electrifcation output: 4HZ, MAX ±27V, 100K rheostat to adjust the output current, the same as the original circuit parameters.

Colloidal silver production: output voltage 27VDC.

Zapper: 30KHZ  ±10%, 27VDC, 100K rheostat to adjust the output current, which is three times more energy than the 9V output of Hulda’s original circuit.
