Hello Illya, interesting insights.
Do you have a schematic (reverse-engineered) for the replacement circuit of the ELANTEC comparator?
I guess it's only that fast new 5V comparator (T.I.?), which is supplied with only +/- 5V instead of +/-18V?
I guess, one could design a replacement board out of that for existing old analogue PCBs.
i have a white (slightly damaged) front panel for you
