On the topic of monochrome monitor fading, here's some more information,
received from KREYMER@FNAL.FNAL.GOV:

"I have seen this problem on many monochrome monitors over the last couple
 of years. Thank you for the solution to an old, nagging problem !
 I have installed the suggested zener diodes on one of my monitors, and
 the problem has vanished as advertised.  Inspired by this success, I
 tried a similar, simpler solution. I have installed a simple 33 kilohm
 resistor between B2 and ground. It draws just 2 milliamps, which is enough
 to keep the voltage between 68 and 72 volts. The screen is just as stable
 as with the zeners, and 33K resistors are a lot easier to find then 72 V
 zeners.  Any value from 33K to 100K seems to do the job."
