What is the spec of the -75V? I can find no mention of the tolerance of that (or any) voltage rail other than +15V.
What leads you to think that a 7% error in the -75V is the source of your bright and uncontrollable intensity trace? And what makes you think that an error in the HT is the cause? If it is low in value, there is less acceleration voltage and the trace will be dim or unfocused.
