Tubes?

[turbo]

now that is called a magnetostrictive oscillator.

hello all i did find somthing of intrest last night as well

might it be tpu secreats?

hummmm oh i think so

and it is about phase but i think i will let the rest of the world find this one 

is

ok i have posted other things that will help if they havent yet they will but i might as well post this too because how long will it be b4 this gets posted who know but it is key to the tpu

why is phase key?

well more than just making the mags rotate btw 1 group of controls go 1 way and another spinn another way remember the quote from sm  wich implys this? if we had a ball and it was seperated in the center and we could spinn it in 2 dirrections what would the remifactions be?


hummmmm

phase is more than the on pluse jumping around the ring there are  trailing  things with phase out of phase of the first pluse by 90 deg or a quartor wave hummm current? to the feedbacks  from a quaterwave humm also the perpendicular thing does that work hand in hand with phase oh i think so when i get to it i will post what im talking of


but maybe someone else will first i sure hope so

is


isnt  the highest Q osc a crystal?

just a thought if we can take 3 square waves and make a sine wave can we take 3 sines and make a square wave?

so after reading what it says below  applyed to the tpu  feedback coils wound over all others and 3 or 4 of them depending on config of coil  like gk4 4 will be easyer to understand right now  so we will have current in the feedback coils but it will be dc right  from the lower ring spinning 1 way and the top spinning the other way now when the 2 currents come togather insid of the feedback coil we will have positive and netigive gian of current in the feedback when both pluses are in the same feedback coil

im out there but i think that is what is required to progress this project                      "the out there thinking"

when the coil is set up as below then the current phase will be shifted by 90deg so the feedback coil will have current the 1 behind the 1 being plused so that is how our beat freq works as i think  have the beat so it corasponds with the phase of the current  so both currents are in the coil at the same time making pure dc current!!!

now how is that

i will get there trust me but it wont be alone as i laque most of the skills but i will learn them

is

thinking i wont crack it ..... gall darn it i will ........ cuz im mentaly ill ........ from crazzzzy vill......   

just some eminem the ~~~~ist~~~~~      way

Some folks here ought to be working with 12V tubes, rather than the 200+V ones!

Check here for some good info on them:

Agreed!

I'm experimenting with some 8056's out of my R390a right now. Excellent link! I've been looking for that info and the Duncan link on his page. I want to try some Thyratrons as they can handle a high capacitor discharge and switch off completely once plate and cathode are at the sam potential. They can also be biased to switch on at a selected voltage - even a small voltage.

@Z_P_E,

Do you know of any thoriated or cold cathode thyratrons?

I used a variation of the attached while experimenting with magnetic rotation.
A good place to visit for much detail and examples of many circuits is http://www.vias.org/basicradio/basic_radio_15_09.html .

When I used this circuit I doubled it and connected them together as a multivibrator. The unique thing about this is that the frequency is highly dependent upon the magnetic resonance of the core and much less on the resonance of the coil. The coil of each tube circuit can be split into adjacent control coils.

I have some doubts about SM using it as I strongly believe he had two sets of tubes. Each set consisted of a triode and a diode. I suspect a triode or dual triode because the photos appear to show a metallic base tube. This would mean it was rated for UHF/VHF. The second tube appears to have a separate plate cap. This could mean many things but at that size of tube it usually meant it was a high voltage diode.

That would probably mean he had two blocking oscillators wired together as a multivibrator so they would alternately pulse one time each.

How would he get two pulses out of each?
The two coils of each circuit - each located 90 degrees apart would appear as two pulses - one lagging by 90 degrees.

How would he get two freqs?
Each half of the multivibrator circuit could be different by turn count or core mass so each half of the multivibrator would complete its cycle at a different rate.

Where is the third frequency?
The difference between the first two pulse rates would create a component equal to the difference between them.

What about one collector being higher Q than the other?
You can increase the Q factor of a coil by applying feedback from another coil(a tickler coil). The tickler coil is generally much fewer turns and carries a much higher current than the other coil. How you apply this info depends upon your idea of coil layout.

I hope this helps. At a minimum it should provide interesting results.

The basic radio hoag jpg ist wrong.

+ Batt is directly connected over the Coil (L1) to the ground (-B) so that this an "shorted" Voltage .
This L1  mus be powered  from +Batt
the way that connection are :
+ Batt - L1 - Tube Anode.

L2  -Batt - L2 - G1   ist OK.

Usually for L1  is used L1 with (varible) or fix condensor in paralell ,
this way to have an fix and constant frequeny.
(do not forget the heater voltage additionalle.)
