Re: [TCML] A New Kind of Valve Coil

["Peter Terren" <pterren@xxxxxxxxxxxx>]

Sounds like 2011 is the "play-with-the-power-envelope-for-super-swords" 
year.

Great stuff that Steve and yourself are doing.

It would be interesting to see the spark growth with a streak camera where 
you can see events down to 1 microsecond resolution.
There is a lot of detail there to be seen with spark gap coils.

I just wanted to share my project of the past few months with the
list. It's a new type of valve coil. Gone are the microwave oven
transformers, and in their place is a digitally controlled power
supply. This is basically the Valve-based answer to Steve Ward's QCW.
Credit goes to Steve Ward for help with the design of the frequency
modulated SLR power supply.
