LV side ratings
Hi Gauss,
I have used two different inductive loads.
The first was a coreless spool of fine magnet wire maybe 28 gauge. I put a ceramic magnet inside the middle and have seen subtle movements on the magnet with some tests.
The second was a small coil with welding rod for the core. I sat a ceramic magnet on top of this core and had it jump a few inches on one test that was difficult to replicate. But that was enough to see that the concept of the Gray Tube worked and the diode definitely has to have the cathode towards the LV rod.
The LV side I believe can be any voltage as long as it is just LOWER than the HV side. If the HV side is 4000v then the LV side can be 3999 conceptually...but I would keep it much lower and higher capacitance. Gray used a 12V battery...assuming standard car battery and similar amp rating so I think for the real Gray Tube replication on the same scale, a 12V car battery should be at the LV side.
If anyone wants to experiment with the Gray Tube and use an Ignition coil on the HV side, I'd use around 400v and 4~couple hundred uf's similar to the LV side on the water sparkplug circuits.
