Hi All:
I remember something about an limiter circuit to limit the anode current, when driving the CRT hard (displaying a bright trace). That circuit was supposed to keep the maximum brightness to a safe level and to protect the MCP from aging too fast.
Don't remember any CRT timer... or warnings about limiting brightness... could be an option in the software?
Also, if you run the self tests, you can see how many times it has been powered up, and I think... the total number of powered on hours. (the lower the better, for CRT life.)
Best regards and wishes.
