So, as is common, my 4000A monitor has dimmed with age. And when it is first powered up, the edges sort of wobble (slightly) until the monitor warms up. The monitor has to be set pretty close to max brightness in order to see what's displayed. Just wondered if recapping the monitor's board would resolve some of these issues.

Recapping might help with the wobbling picture (se http://www.asterontech.com/Asterontech/NeXT_MegaPixel_Restore.html). For the brightness you could try the adjustment pods. see page 42 of NeXT Hardware Service & use non conductive "screw" drivers
