RE: tube coils

Hi Greg
You can put some of those tubes on ebay to raise money for tesla coiling.
There are a fair number of tube collectors. MINT condition tubes sell for
good money.
Go to http://allencoilpage.home.att-dot-net where a 60 kV transformer for an
x-ray diffraction machine was modified to a powerful tesla coil power supply
capable of 20 kV and 400 mA. That is definitely pole pig country.
If you decide to keep the x-ray power supply for high voltage experiments,
try to find the manual that goes with the machine. These x-ray power
supplies can be quite confusing without the manual.
