Tubes?

[joe dirt]

Another upside to using tubes is they will survive any massive CME or geomagnetic
   disturbance, as compared to the static sensitive fets,   of course you might buy
   the hardened ones made with synthetic diamond, but I think they will be hard to
   aquire.

If you can do it with tubes then this is the best option, they are much more har har
   hardier

A few Tubers!...simple things really ...just bitey!

Use one only hand at all times....and it will just hurt a lot!

I have been told that a tube circuit can be attached directly to a "coil" and it will tolerate the massive harmonics generated by the interactions with out damage.


this "suggests" that no transformer was used...however, IF a transformer was used it had better be able to do 245 khz..

6as7g tubes were used in his first experiments...this also suggests freq below 300k... in fact it is hard to get these tubes to 300k. you may find it difficult to find an output transformer that will get to 300k as well.

Those with more tube experience could help here?



another good thing about these tubes is that they are happy at 150 volts and lower....a bit safer?

My suggestion is to use a dual triode driver and commom the two triodes in  the 6as7 to increase the available current. feedback/syncronisation from your mass of wire at the correct point could be important.

I am working on a blocking oscillator arangement ..the tpu is the tuning transformer.

I know that all of this points us away from nanosec sharp pulses! However it may be more about how they react in the grid circuit for sync, than how fast the plate pulse is.

I cannot over stress the importance of using a 15" ring for this section of research.

time, and lots of participation will  help

we are actually trying to make a circuit that will try to self destruct .

Ah, I see!  We'll use sine waves then?  In a sine waves setup, what function do the tubes serve?  I'm used to seeing setups where the tubes act as switches.  Actually, where the MOSFETs act as switches seeing as no one is using tubes yet.  (Except a select few I guess)  I'm thinking a ramp up like they use in inverter circuits where they use transistors or whatnot to step up and down the signal and smooth it out to look like a sine wave?  Or is there something else...  I personally am going for the 3 colector approach based on those letters.  Series connect them if everything works out.

i think the tubes act some what like an electric amp the electricty will grow in the tube and end up making a stronger mag feild shock wave into the collector that is resonace cuppled to the transmitters read all 4 pages i posted please!!!

what i get out of that is this

basicly we pinch 1 tube then the other agin and agin each pinch increases the current in the tubes if you read what i posted from the book i was reading you will see how it relates the circuit must be verry simple like the eric dollard vids the phase invertor will cancel the flux will it not out of phase by 180 deg the pluses will colide inside the wire

also in that same book was somthing lke a mechanical tpu and at high speeds it could produce ofer 200kw works on the same o p but with mechanical input but we can easly sub mechanical for electrical revolving magfeilds this generator i spooke of has no tubes or circuits involved in its operation purly mechanical i beleave  this produced high freq ac current wich can easly be switched to dc right!!!

btw im kind of wondering if in fact the fets people are using should be used as switches at all!!! maybe some one should hook 1 up as an amp!! like a car amp i found many circuits there was another one that talked of supplying the out put of 1 tub through the coil into the input of the next hummm

like i said read the old books for the truth then apply it to what we already know 

with a great efford like this how long will it take to crack this ...................           not verry long

1 more way we colud look at this is there only so many tube circuits 

ist

there was 1 more circuit i felt fit the application as well  it was a multi vibrator circuit with 2 triodes so if we use dubble triodes i guess we have  2 oscolaters  in 2 tubes for 2 beat freqs for 2 rings and the 3rd is output does that fit? works similar to the last 1 i posted  it sounds like to me any way that when we get this togather it will start from the swipe of a magnet if it is tuned close to 7.8 after the heaters are powered of course and also thease are not the regenerative circuits i spooke of b4 eather those are diffrent agin from thease

Let's hope we do not run out of tubes from our experiments!
