Anyone tried using a CRT rejuvinator on these to improve cathode
emission?
*** IMO the most common failure mechanism is not lack of cathode
emission but lack of light emission from the target.A simple test to
carry out on a low light output eye is to increase the heater Voltage
while it is operating,most times there will be no increase in light
output.
