-GE 1000 dental x-ray head 
- 
-I was told this head was from a GX 700 but I think its actually a GX 1000.  This also matches the case markings better.  I think the terms "GE 1000" and "GX 1000" are interchangable 
- 
-Why: got Gendex USB x-ray sensor on surplus market and trying to make a PCB x-ray inspection machine

-====== Tube ====== 
- 
-The control boxes indicate its a 100 kV, 15 mA tube.  I get the impression this is unusually powerful.  I tend to remember someone said this unit is too powerful to use in modern dental offices but should be fine for PCB inspection 
- 
- 
-====== 46-158800G2 controller ====== 
- 
-Master control unit.  Provides correct voltages to up to three tubeheads

-From [eBay 291057383064]

-Provides remote control, came with my tubehead.  The main controller was still in use for a bit longer so wasn't able to take it but might be able to get it in a few months 
- 
-15 mA and 10 mA scale.  Someone mentioned that 
- 
-TODO: measure meter to see what voltage it wants
