Re: [TCML] hybrid coil

["Carlos Van Camp" <carlos@xxxxxxxxxxxxxxxxxxxxxx>]

well I definately need to try out the stacatto method.
anyone recomend the best place to get a stacatto board that has sound input, 
and duty cycle control?

Thanks.

Carlos,

As Steve mentioned, the main ways that staccato operation produces longer 
sparks
for a given input power are:

 1)  The intermittent sparks grow longer in air due to the nature of spark 
growth dynamics.
      (The use of raw 50Hz or 60Hz AC to the plate will also give longer 
sparks than the use
       of filtered DC.  Staccato gives full control over the pulse rate for 
even better spark
       growth "efficiency".

 2)  A lower tank impedance can be used to put more energy into each pulse 
resulting in
      longer sparks for a given average input power.

There's no need to raise the plate voltage.  In tubes that run with red hot 
plates, it's true
that staccato operation lets the tube run cooler, so higher voltages can be 
tolerated than
otherwise.

Cheers,
John





Many people have said that stacatto only helps get bigger arcs by allowing

you to run higher voltages on the valve.

I am already running 10kv (which is the valves maximum rating), and I don't

want to push its rating because I want to be confident of its reliability

for my client... and also because a new valve costs around US$1500!!!
