Subject: Q: X-ray tube filament (s) voltage?

Hello All,

Any one here that can shed some info (namely the filament voltage) on the below listed X-ray tube?

It came out of a recently declared surplus GE Medical Systems unit. Model Z.1B2b1,4a51. Type: 39558014
Tube Man. date Jan 1994.
Nom. Voltage 49 Kev - it contains a rotating anode.
Inh. filtration = 0.8 mm Be
Focal spots = 0.1 - 03 mm

It has two filaments...each filament goes through a diode. It appears like a faint attempt to isolate the two separate filaments inside the X-ray tube.
The resistance, past the diode, and directly across
the tube filaments(s)is too low to give a meaningful reading. Any suggestions for the filament voltage - or
anyone interested in buying this used x-ray-head?

Thank you, Joe

BTW, I was unable to get this info from GE Medical Systems on the www. They rather sell a new tube. :-)
