GK, I've finished winding the control coils on my GK replication TPU.

But I really need clarity on the circuit.

You have said you have 3x 100ohm 1/8 watt resistors, 3x 100 ohm 1/4 watt resistors, 6x 10 ohm 5 or 10 watt resistors (2 in parallel).

Basically I just need you to give your complete circuit, including 555 timer caps and resistors and single turn pots and all.

note: I can't get tip41a, so I got mosfets which I will drive with a push pull transistor pair.

@GK,

Otto said from the opposite end of the feedback coil that connectos to the collectors and the negative rail of the PS.

BTW, almost there, I am using all copper.

His diag I used has the feedback between the positive rail and all the outputs of the controllers not the collectors.

Now if CU is less resistive than FE you should get a more responsive snap which gives you a bigger faster field which gives you a faster effect which heats up the CU, Huh?

Than makes 1 iron core and 2 copper core. This ought to be interesting.

Build a cage!

I thought that the one end of the collectors (all three) are connected to one end of the feedback and the other end of the feedback was to the positive rail.

He said in his post to conenct the load to the negative rail and the connection point where the feedback coil meets the collectors.

I could of mis interpreted his post but that is what I got from it.

Yes it should be interesting..

Fast pulses from groung to +v.
100 ohms to base.
collector to Otto's coil config. The hi watters are in the diag. and the freeback straight to +12v
All the 555 resistors are 200k pots, 2 per. duty and freq. the caps are 2.2Uf
Glad you are close. Gonna stay up late? I think so!

Look at the diag the clockwise outputs are connected together and no where else. I thought so too. The ends are just connected togther and nowhere else. Shorted!
Get those jumps on now and then get to the next jumping.

We'll cover the load later because I don't have any negative. If you do you cancel any field generated.
