user TURBO?s replication of Steven Mark?s TPU ?

X,
1-Are these pictures of two different "TPU"s?
2-What do you used to wrap your coils on?
3-How do you fix your collector in the form? I have a feeling it must be some how kept in the center of the tube or whatever. ( like a co-ax wire )

Its the same TPU at different stages of construction.

I dont use anything to wrap the coils on.  The collectors are self fixed, ie they are wound and taped, then control coils wound over them and taped and then each layer is placed on top of the other and taped in place, then an outer coil is wound over all of them and taped in place.

My Goodness..... I'm speechless! This writing is classic!! You surely need to publish this into a book when you are finished!!

@Mramos,
please post again the link to your programmable three output driver circuit. I am at my PDA only right now, so I have limited viewing capability. Thanks.

I guess the TP U has merit. Yeasterday, when I was tired I connected some coil components of it together and suddenly had a much brighter LED lightning. I thought, well, it is probably just the brightness of the direct output of my function generator and did not write down, how I wired it. Today I rechecked the function generator and I see, that my LED is pretty dim with it, when I drive it directly from the output. The function generator puts out only plus-minus 5 Volts, so 10 Volts peek to peek, but the current is very limited and the pulse pause is always 50 %, so as only the positive wave lights the LED with this duty cycle, it is pretty dim at all frequencies...
Now today I don?t get the old circuit connection not anymore.. too bad I did not write it down, which connection I did exactly.. So this configuration did put out at least 2 or 3 times the power fed into it, if you compared the brightness of the LED...
I think I had some kind of feedback loop with the center coil...
