Hello All
i am trying to repair the intensity control cct fpr a tek 5113
spent several days no joy. I am getting the neg pulse
all the way to the z axis amps. out put Z Axiz, full amplitude 70V peak
on both. Amplitude can be varied using brightness controls but the
grids remain at 3.4kv all the time.
Checked all cpmponents around the restorer cct all looks and
measures ok.
What is the function of the neon lamps?
Any Help most appreciated.
Thanks
