Successful TPU-ECD replication !

[otto]

Hello all,

@Nick

I know what youre speaking about. For me no setup for a TPU is complicated. Its only a lot of work to make the controls and specilaay the collectors.

About the SS board I can say that the function of such a board depends on the weather conditions. When its hot and dry then OK but when its raining.....

To all:

sorry guys Im a looser with tubes!!!! Im not able to build tube oscillators!!! I need heeeeeelllllppppp!!!PLEASE!!

I need a schematic for the power supply and a schematic for the oscillator. I think for sine waves. Something that works!!

I have 3 12AU7 (ECC82) tubes. Please help!! I had a few shematics from the web but I wasnt able to build this oscillators, they didnt work.

The point is that I have soooo f.....g coils that Im blowing my MOSFETs without any problems. I think that there is NO MOSFET that would work in my coils and so I MUST build tube oscillators. They are NOT overheating or such a disaster they are only pumping my .....hmmmm....copper coils with a little current from my power supply.

Yes, I know how tubes work but just give me a schematic so I can continue in my work.

Think about me what you want but fact is that Im not good with tubes so.....help me.

Now a question: we cant blow tubes?? I hope?? I know your answer but you dont know me!!ha,ha.

Here is a link that may help. They have lots of circuits for tubes. I will list more here as I find them.

1) http://www.angelfire.com/electronic/funwithtubes/Amp_Design.html

2) http://faculty.frostburg.edu/phys/latta/ee/6cl6xmtr/6cl6schematic.html

3) http://www.geocities.com/SiliconValley/Pines/5440/
Another page on this site on Geloso, do a find for "12AU7".

4) Go here http://www.mif.pg.gda.pl/homepages/frank/vs.html
and do a search for 12AU7

5) Introduction to tubes
http://www.ibiblio.org/obp/electricCircuits/Semi/SEMI_13.html#xtocid1562411
A quote from the web page.
"The closest semiconductor equivalent to the Audion tube, and to all of its more modern tube equivalents, is an n-channel D-type MOSFET. It is a voltage-controlled device with a large current gain."

6) Good site for all type of circuits, but I don't know if there are tube circuits.
http://www.ibiblio.org/obp/electricCircuits/Semi/SEMI_13.html#xtocid1562411
Thought I'd put this in anyways because of the extensive listings.

7) Jackpot - Loads of online books on vacuum tubes.

@wattsup

thanks. Now I have again to play with tubes.

Hi,
I am new to this forum so I have had a lot of catching-up to do reading previous posts!
I must say, there's some impressive work being done here by all the experienced EE's which makes me envious; I'm not an engineer just a lowly technician. Maybe this makes me an ET?

Much of your work so far seems to have been concentrated on the output circuit and very impressive it is too, but I haven't seen any reference to the "free" energy input that SM demonstrated.

From the video's I was struck by the fact that SM used a magnet to activate the unit, this reminded me of something I read on Tom Beardens' site about charging a capacitor using a permanent magnet.

I don't know if this is relevant but I thought it may be of  interest.
