   Maybe you can persuade Steven to come forward and take credit for all the work he did back in 98.

Hello all,

@Nick44 and all

Without a discussion: TUBES!!

I saw it in my 2 years: MOSFETs are really dirty. A lot of hash, a lot of heat, a lot of s..t.
When Im mixing my frequencies I see a lot of times that my bulb "wants" but the SS oscillators shuts OFF!!
Then I see when my signals are clear, without hash, my bulb shines like a champ.

Of course there are a lot of other reasons to use tubes:

1. SS oscillators

signals on the output = 5V - 12V or a little more - this is the "start" point - this signal is feeded into the TPU
from the power supply 12V - 50V/ 2 - 5A

5A when you totally missed the frequency mix, or you have a short in your coils or....

2. tube oscillators

signals on the output - plate - say, from 200V and much more - THIS is the new "start" point
from the power supply you can have any voltage you want!! Higher voltage, less current.

I really dont want to teach people here. They are really good!! But....

If there is a little Tesla in our forum I want to ask because I dont know and I didnt see it:

How can I build SS oscillators that can gives me signals in hundreds of volts?? Hmmm....maybe wrong question.

We all have signals swirling in out TPUs from say 400V and up - I have 1200V! just with coils.

This signals we got from our SS oscillators that gave us 5 - 15V signals and MOSFETs.

As Marco is quiet, not posting his results, Im asking myself:

Whats the level of the voltage  IN THE TPU when I use tubes?? We all know that the coils rises our signals. Yes, I know, it depends also on the voltage from the power supply. THIS IS THE GOOD NEWS!!!!

Im not hanging anymore on the voltages from 12V - 50V DC from my power supply!!! Im free to try voltages that I WANT!! In this way I can play, I hope not forever, ha,ha.

What Im talking about??

Didnt "dfro" say: rise the voltage from your battery?? Ooooo, I have a "special battery". But I can use it only with tubes!!

The people here in the forum have luck: if my English would be better I wou much more post but...

@all

Like I said before... If you want to use tubes, USE tubes! SM in the videos wasn't so I am not......

@Sparks

 If you are silly enough to do what you propose in your "schematic", then you better do some research on X-Ray production, as you may leave a nice picture of your bones on the wall! (I post this for safety)

@Otto

You had better research the same. (concerning X-Rays) Too high of voltage and tubes don't necessarily mix.

@all again

Radio fields and electromagnetic shielding are the least of our worries!

Nobody building TPUS needs to flop like a fish due to electrical shock, die unnecessarily from cancer due to an X-Ray bath, etc., etc., etc.

Be safe people.

In my various hobbies, I HAVE been subject to dangerous levels of electrical shock, and it is NOT fun. I have awakened laying behind a couch, because my arm brushed both a frame ground and the wrong wire at the same time. I have had to check to see if someone needs CPR, because they bumped a primary of a working Oudin coil. (Thank goodness it was a tiny one. Probably only 80 or 90 joules, instead of 600 or 1000....) A man I knew is dying from cancer due to X-ray production because of a laser he was building.


I have designed and built everything from quarter million volt tesla coils, to higher amperage lower voltage oudin coils, to 5000volt much higher amperage D'Arsonval high frequency autotransformers. I have built Van De Graff, and Wimhurst electrostatic machines. ALL OF THEM ARE LETHAL. There is no such thing as SAFE electricity.

Concerning High Frequency Electricity...... this stuff is particularly deadly. Not necessarily from the direct shock, but the induced fields and unwanted particle emission. The person whom thinks otherwise will end up taking a dirt nap sooner or later, just a matter of time.


Consider anything with high voltage lethal, and anything with caps even though battery powered as dangerous. When working with voltages above 110, USE ONE HAND, with the other in your back pocket to keep it completely out of the way.

Safety is no joke, and what we are working with here can be dangerous if not lethal. Assume lethal, to minimize it's danger.

Sorry, but this needs to be stated.

      The first thing I did after taking the tv back panel off was to check for a shield around the flyback.
No shield.  It's a small set.  I place a small flurescent there that lights up.  Trying to grab some of the xrays there.  Then I series fed the crt through a small  flurescent and it lights up.  I'm up to about 10 watts cold electricity at this point..  Then I wound a 4 turn bifilar around a 40 watt 18" down placed one end near the flyback and fed the coil on one end from the flyback output,  it lights up between the flyback and the coil pretty darn bright. Now I think I'm up to about 15 watts illumination. Plus the crt and all the other goodies the flyback drives. 
    What did I learn from all of this?  High voltage stressed space gets cold. Bulbs are lit but they are colder than the surrounding air. There is plazma inside the flurescents so they should be getting hot.
Cold plazma.  Maybe the aether is a cold plazma and the electric field keeps it dispersed enough so you don't see any temperature rise. There is a shitload of energy in the plazma but it is not relavent to anything until we mess with it's stratification. hmmmm

If this person had cracked the TPU - he would know how to contain the energy - the field.

@ Marco

     When they get working right does the collector get cold while the emitter gets warm or vice versa?

   @Marco

    I'm referring to  normal dynamic operation of the tpu.
