My power supply.... Blackstone/Ney Multisonic 400watts RF
Nice equipment, FI3.
Just had a look at the Gordian Knot pdf.
Thats full of interesting info!
Thanks for sharing.
As you know, not many people are into researching the piezo options of Stan.
The pdf's who are showing for example the resistors at the tubes are not well discussed on the internet, i think.
Thats why i think you might be on something here. Just like the Ravi coating..
