Hi otto,
Could you post some pics? If you flipped it and was not working that's a good sign, right?
Thanks

Hello
sorry Im not reading carefully

@Dave

the TPU has only the control coils connected nothing more. The collector coil is "in the air".
I dont know if it is worth to mention but when I switch my radio to AM (500-1500kHz) I hear my TPU switching. Ok, I have a really good transmitter because the signal is very strong and at all frequencies on AM.
When my TPU is disconnected (all in and outputs) on my radio on AM I can every few seconds hear a loud bang. When this happens I can see on my scope a very big kick. This is not a man maid bang and the time between the bangs waries. I dont know if this is important.

Hello

@Mannix

you dont know how I like your good night story. I reed it every day 10-20 times. I saw that this story is the clue for me.

Hello

@Mannix

excuse me all but im tired and not reeding carefully.
You said one frequency at a time is important. Yes, I pulsed the TPU with low frequencies at 1-10 Hz and I saw that with a little input signal from my function generator I get a big voltage at my collector coil. If 1 frequency is stopped and the other,so to say starts there is something going on.
In this two days of the weekend I saw such a lot of things going on that I cannot tell and remember.
Yes I remember the kill switch when I feeded the signal from the transformer coil to the "original wire". The signal I got was amazing!!
