Stanley Meyer replication with low input power

[Duranza]

Hi all.

i stumbled across this site a few days ago via youtube, and i must say, this is some pretty amazing stuff. i'd like to build a replication, but im not sure about a few things.

are all the 555 timer chips interchangeable, or is the NE555 imperative to use?
is the alternator in the d14 setup used to power the rig? What is its purpose? (i have a small engine i may want to play with)
is the input power controlled or just let the rig pull what it needs? i don't want to overpower while conditioning tubes.

i've built a number of pc's, but nothing like this. any help is most appreciated.

any 555 chip will do. the alternator is not necesary as you can use a battery or charger to power the circuit.

ty much!

I think the problem is with some folk seeing the mosfet as being part of the magic, when in fact the only true critical components are the coils and tubes, the rest is generic electronics, mosfets have extremely low gate current, but it would be possible to use a Darlington bipolar transistor in it's place so long as it has a fast switching time, as for the 555 timer circuitry, thats just convenience, you can provide a square wave at particular frequencies from a number of different sources.

Well said RunningBare, I think a lot of people over stress on the need for the BUZ350, Probably because the name sticks in your head and is easy to remember, There is nothing special about it compared to any other 200v N channel mosfet.

I do think the mosfet might matter....At least as far as the drain source diode goes.
I think your diode in the d-14   circuit needs to be faster than the mosfet blocking diode  so the back emf pulse will stay in the loop and not go to ground.
The buz-350 has a reverse recovery time of 180 ns and the 32n20c has a reverse recovery time of 265 ns witch is slower. This should work fine in this circuit.  Also, the 32n20 has half of the internal resistance .06 ohm so it should run even cooler than the buz-350..Looks like a good choice and it is cheap. Most ultra high speed diodes have a 50ns on time or less witch should work well in the d-14 circuit. The diode could somewhat effect the tuning of this circuit.
This is just my opinion, I could be wrong!  I will know soon after new my tubes get here.

The back EMF from a coil of 100 turns on a ferrite core would be in microseconds to milliseconds, a delay of 180 ns would be insignificant.
