Successful TPU-ECD replication !

[otto]

Hello all,

@Jestes

I can only say that tubes are a MUST!! Sorry guys with MOSFETs. For myself I can say that Im on MOSFETs and building my sine wave oscillators with tubes. I burned a lot of MOSFETs and finally after over a year Im now cleverer.

TUBES, nothing else.

About the coils setup I can say that my ECD coils can be made very easily and fast. But I also have to say that this coils are made in a wrong manner. Our Master said: all around the collector in segments, if my memory serves me well. The ECD coils are overheating and this is the main problem. I had great results with the ECD but the heating...

Of course, when we have the right coils connected in the right way and everything is working, then we have to use SS. Yes, I didnt say MOSFETs but SS!!

Hello Otto & All,
would you mind to compile a new schematic that contains the last modifications from the version 1.0 (your PDF) please. This new schematic could show us how to connect TUBES to COILS,How many coils,building details of coils,collector, .

Otto, if you put your TPU in a "shielded box"(alloy box fo example)and scope the output signals, and later, you put you TPU "out of the box" and compare signals (after an before) . Which will be the difference between and after measures?. the earths must causes some effect. I want to promote these effects.

"TPU have gyroscopy effec`s"... then, how could we build a gyroscope with a coil an "kick's"?.

sorry for my bad Inglish.
B.R.,

Im using a ECC82 = 12AU7 tubes.Double triodes. 3 of them for 3 oscillators. Heating voltage is 12,6VAC.

Of course, youre right. Output should be sine waves. Yes, the tubes will be a part of the TPU.

The point is that I now "convert" my kicks into sine waves directly on my bulb. The input signals are square waves (kicks) and at my bulb I have connected a oridinary cap that converts my signals. I have arround 200VAC on my bulb. OK, input is 12V or 24VDC from the power supply and the current is the same 4-5A. And I saw that I can mix my square waves in the coils and have a fine output on my bulb.
With a voltage of say 250V from the tube it would be interesting to see whats going on in my coils. Yes, I know that the plate voltage is only in miliamperes but there is a heater with his current. So, when I connect the plate VOLTAGE and the heater CURRENT.....so they work together....50Hz + a high frequency...I dont know what will happen. For sure I know that there will be a vibration because yesterday I feeded a unknown  AC voltage (12V??) 50Hz to my pulsed coils and I had a vibration.

Hi Otto.
I did a google search on the ECC82 valve, and "National Valve Museum" came up as one website.
Made me feel like I was stepping back in to the dark ages    *grin*.
Mind you - It was designed in the late 1940's.

It did state that the ECC82 had a stated gain of 17, compared to the ECC83 (12AX7) which was 100.
Any better for your application ?

You're right - It has a centre tapped heater, so can work on 6.3 or 12.6 volts.
For some reason I just had the figure of 6.3V in my brain.
Maybe I'm more rusty on valves than I thought.

You say "I have around 200VAC on my bulb".
Did you mean DC ?

They are also Double Triodes as you say - 2 independent valves in the one package.
Are you using both halves in each valves, and in which mannor...
IE: Are they individual, so 1 & 1/2 12AU7's would give you 3 useful valves for the 3 frequencies,
or are you just using 1/2 of each 12AU7 valve ?
or are you using each of the 2 halves with different frequencies, but with a common plate resistor, to MIX the 2 frequencies across it ? (for a single output).

I'm not exactly sure how you are meaning to set up your circuit from your description, but that's ok.
I'm sure things will become clearer for me with time.

You said "I feeded a unknown  AC voltage (12V??) 50Hz to my pulsed coils and I had a vibration."
Perhaps it is just the 50Hz that is the vibration you had (?) Unknown.

HI LONG TIME NO SEE
HI OTTO THE  ECC 82 IS STEREO PREAMPLIFIER  WHAT YOU THING WHAT YOU CAN MAKE WHIT THIS TUBE MORE THEN IN OR ..... BUT LOOK IN THIS WAY  IF YOU READ SOME OF IS Y
S.M SAID SOME TV RECIVER IS EXPLODED AND KILED THE BOY  HMMMM GOOD IDEA    YOU GET THE HOT TUBES  AND SOME HIT THE GASS OF TV LIKE 27KV  WHIT KATHODA 200VOLTS WHIT 6,3 VOLTS HMMMM WHAT A ENERGY
27KV +200V+6,3= ?   IS YOU GET SOME EXTRA ENERGY  ORR
I SAI THIS  YOU MAKE TERMO MOVINGS ELEKTRONES    AAAA HHHHH WHAT 

[innovation_station]

i only peek in here once in a wile nice to see you have tubes otto



dont hurt yourself

ok well how about a magnet!!!!  forget the ss forget the tubes  maybe just a magnet hummmmm....

well maybe a cupple more parts lol

why osc's why ss? why tubes?   i have said this we are forcefeeding  just try making it   : with a magnet and coils  but remember wire is verry important  and just this quote from the vid

it is just the knowalge of the coils and how they interact with each other  think about that only nothing more  it will come to you all and you will laugh as i still am
