I only use the best parts available on the market. The selection of these components has been made extremely carefully, in order to prevent disappointment in my customers/clients.

If you purchase the kit parts to assemble the device, I recommend to have some advanced knowledge of electronic component assembly and soldering as this is not a beginner project.

I would like to emphasize that the voltages existing in the circuit can cause an electric shock which could be potentially lethal. Therefore, I cannot be held responsible for any accident, or injury resulting from the use of the circuit.

If you would like any further information, please do not hesitate to contact me.
