Re: [TCML] SSTC (and VTTC)



Hi Neal,

Some tube info at:

 http://www.vacuumtubes.net/How_Vacuum_Tubes_Work.htm

Basically a VTTC is an RF power oscillator feeding a resonator.  A power
oscillator is an RF power amplifier with feedback.

Hi John, 
 
Thanks for the reply. One more question (for now) re: tubes. Can you or anyone recommend a site that can give the basics of tube operation? Aside from putting the parts together, I'd like to know what, exactly, they are doing, how, etc. Thanks! 
 
Neal. 
 
 
Neal, 
 
Yes, a VTTC is easier to build than an SSTC because the components are 
larger and less finicky in some ways, and mistakes won't cause the 
components 
to burn out as easily. I have some VTTC's and schematics at my 
websites at: 
 
 http://futuret.110mb.com ;
 
and at: 
 
 http://j.futuret.googlepages.com ;
 
I just completed a small VTTC project using a 4-125A tube powered by a 
small 
MOT. The project gives 7" sparks. I just added a couple of new photos 
showing the completed project. It's just a basic VTTC, nothing fancy. 
 
An advantage of VTTC's is that the RF is less destructive to household 
ap
pliances, computers, etc. After the VTTC is completed, you can add 
the 
staccato (pulsed) feature if desired. Building the staccato pulser is 
an easy 
way to get involved in solid state projects. The staccato pulser is a 
solid 
state add-on to the basic VTTC project. 
 
There are many other solid state schematics available on the web also.
