Anybody got some schematcs or ideas on how to fire up the soviet e-bay
klystron K-166(Gamma)3 9102??, seems like part of some resonant cavity
gizmo.
Filament 6.3v 0.5-1.3A
Resonant voltage 350V
Negative repeller voltage -50 to -350V
Repeller circuit not more than 100kohm
Load SWR 1.2 Max
Cathode current 10ma to 50ma
Frequency stabilization time 5min max

Why try to lower the frequency of the Klystron how about increasing the
frequency of the TC.
Or better yet, how about frequency modulation where the Klystron is the
carrier wave.

I was meaning "Could" in the broadest possible sense.. Klystrons are
generally "Tuned" and calibrated where they are made and usually come
with a calibration sheet listing parameters and settings because they
don't work very well at other freqs etc.. But "possibly" someone could
design one to work at lower freqs. Just like people use high heel shoes
as hammers - they work - but its not generally a good idea!
If operated in conditions they are not designed to operate at - then
they will be hopelessly inefficient and would likely not even work at all.
If you don't have the original calibration sheets etc that came with
them, then you might never get them to work properly anyway.
Also don't forget that you wouldn't want to plug it in without your non
ferrous (or non magnetic tools) - peoples fingers have been know to get
a little pinched in the big ones when the tool slams into the machine -
They have BIG magnetic fields to contain the plasma...
But to explain my "could"
IF you could obtain two nearly identical Klystrons that operated very
near each other in freq - then you have a good starting area.
No two klystrons are ever the same - its just the nature of the beast.
And considering the lowest practical frequency of klystrons in current
use is about 300MHz - which is 1000 times the freq range of a Tesla coil
- then you have a little bit of work ahead of you - but who ever said
practical limits aren't meant to be broken... after all we fly around in
heavier than air flying machines now....
besides - you are using them to make sparks, not efficient TV broadcasts
on satellites etc.
The beauty of Klystrons is their fine Amplitude and Phase control - if
you could get them operating close enough to each other so that one was
operating at say 300.1Mhz and the other at 300.6MHz - then you could
create a beating frequency of 500kHz - which is a good freq for a Small
Tesla coil...
I'll leave the rest up to you.....
Hey these aren't reflex Klystrons are they? - Hmmm "Homeland Security"
might pay you a visit if they are

Well that's exactly what Klystrons are used and designed for.. They
are designed as amplifiers to drive resonators or transmitters etc
that allow you to boost a signal while controlling the phase,
amplitude and frequency etc... They could be used to drive telsa
coils - but are usually designed to operate in the hundreds of
megahertz or gigahertz range... but like any thing they could be
adapted for other uses....

Well...
Klystrons (like most any amplifier) can be either oscillators or
amplifiers, depending on the circuit it's in.
I can't imagine Klystron being adapted to work at lower frequencies
than it's design frequency, except maybe if you use the control grid
(if it has one) to turn the beam on and off, and use it as a "real low
frequency" switch.
You could also use them as doorstops, which is "another use", after
all. _______________________________________________
