Successful TPU-ECD replication !

@Marco,

Try to make a 20Hz Hartley or Colpitt ... it's practically very, very difficult  so nobody use it

Otto,

After considerable reading of the various threads, they always talk about fast turn on looking for the generation of the RE from the fast rising pulse edge in the TPU device. Now I am hearing that you are trying to use clean sine waves for excitation. Boy did I miss something. Could you please set me straight on this.

Thank You,

John

Hi Ron i do not think our driving signals will go that low.

if we look at the television we see the yoke (especially the old ones) produced quite a large amount of ELF radiation which is intresting because the yoke itself was driven at much higher frequency's.
This radiation actually needed to be shielded and the design of the yoke's changed over time for a specific reason.
i see this ELF radiation a by-product of the combined fields.
it had something to do with a saddle saddle torrodial yoke and they started to make rules to regulate the amount of radiation.

You know John - I have to agree.
I'm not the one building it, so I've kept my comments minor, or kept my mouth shut.
It's not my place in being Negative about it - that really doesn't advance anything.

But I have been thinking the same thing for quite a while now.
It's the fast rising edge of the square wave (infinite frequency - in a perfect world) that is stimulating the coils, and/or injecting a portion of the exact frequency required for the TPU to do its thing.
I've been wondering whether it will end up just being a case of "Throw enough power into it until we get something out".
Get it into resonance & everything will look good, but I probably wouldn't think OU.

Just my inner thoughts - that's all. 

PS: I was wondering if we should start this as a new thread Perhaps called: "Tube Drive for TPUs

PPS: Otto -
         Perhaps you could use one HALF of the 12AX7 for the oscillator, and the other half just as an amplifier. This should Greatly Simplify the coupling to the TPU.

Hello all,

guys thanks for the schematics.

As I have my tubes made in....."high quality"....I decided to first make basic tests with this tubes just to see if they are working!!. When I bought them I even didnt think to get sooooo "good" tubes. They are soooo "high quality" that the producer company name is not known!! HA! Now I have to work with them!!

@John

I had a few runaways with square wave kicks. The best "success" I had when my kicks converted into sines with a lot of hash. As I wanted to get rid of the hash I tuned a little my frequencies and I saw that I had less hash and then the "success" came: everything blown!!!

My other runaways happened in a different way: as I was surching for the right frequency mix I suddenly saw that my loved IRFP MOSFET is blown. In just a very short time, whilst I was striving over the frequencies it happened.

The point is: remember our master words: like a radio receiver. You have to tune into the frequency mix. With sine waves its very possible to do it and with square wave kicks its impossible.Impossible because the runaway happens sooooo quick that NO safety equipment can help you. Of course there is the story about audio.......not to be too long.

Look at the tubes topic where marco showed us the output signals he got. Such signals I saw when I burned all of my equipment. This signals can be made with sine waves + a DC voltage or with coils like the ECD coils....not so good, overheating problems....or with....

@Jeff

why not to start a new thread? Maybe you have the schematic for the 12ax7 oscillator??

Square wave - sine wave. Hmmmm.....I see that I can use also sine waves. SM told us that the TPU works with the earths magnetic field. Fine. In nature is everything vibrating.In SINE WAVES.

Sorry to say but your inner thoughts are wrong. You mentioned resonance but not OU. Remember the videos? Input was ....output was .....remember??? Please, dont even mention a battery.
I cant understand why are people always talking about COP, OU and such things in connection with a TPU??

I dont remember if its mentioned in my pdf or not. Now for the last time I hope:

A TPU DELIVERS YOU SO MUCH ENERGY AS YOU NEED!!!

if you can control the frequencies!!!!!!ha,ha.
