Hi all
I'm new here, but I already have attempted to make the Tesla switch. At that time I did not know much about radiant energy and Bedini motors as I do now, that's why I did not have much success. My circuit looked like this:

(sorry, this picture is not available anymore)
The batteries were 1.3Ah lead/acid type.
The oscilator is not shown in this circuit. Slodze=Load. I tried a
small car bulb (1 Ohm) as a load. The bulb was powered through a
bridge rectifier (not shown in the circuit)
First I tried the switch at a low frequency, about 10Hz, everything
seemed fine, the transistors got a little warm and the car bulb
lighted up, but not as bright as when in direct connection to a
battery. Then I increased the frequency to about 250Hz. The bulb
brightness remained the same, the transistors felt a little warmer. I
measured 4.3VDc across the bulb and 0.77Amps. But after few hours the
the light of the bulb turned weaker and slowly the amperage across the
bulb dropped too.
Now I know, that there are some problems with this circuit. First of all as Rick Friedrich said, I should have used NPN transistors instead of PNP because PNPs allow current through constantly, and NPN only when the trigger Base is gated. Also the load was too big for these batteries. The load should be such that the batteries are discharged in the c/20 rate. That means that the load should draw only 65mA. This is because a larger current draw would cause heating in the batteries and that is not good. Now I will try out the circuit with the NPN transistors:

Maybe it will help someone. Or maybe someone has anything to add?
Edit: I read somewhere that the name "Tesla switch" is due to the fact, that Nikola Tesla gave this information to a friend. Then later this friend of Tesla shared his knowledge with John Bedini. From here this circuit is called a Tesla switch
I do not know if that is how it actually happened.
Thanks,
