RE: [TCML] VTTC-tuning. John got me started ;-) water resistor

["Jim Mora" <wavetuner@xxxxxxxxx>]

Hi,
I have made a few of these to dump the energy of a large discharge cap. Jim
Lux has a write up on making them. He suggests using tygon or vinyl tubing
filled with distilled water doped with copper sulphate which is in most
hardware stores as a root killer. He used brass or copper bolts or brass all
thread in the ends. I suppose for short storage life table salt would be
fine as the resistance will change.

Hi

This disscussion reminds me of oh, long time ago now, didn't Marco Denicolai

make some kind of fancy water resistor hung from the ceiling to do that? 
Whatever happened to that project? I do not remember seeing any results.

later
