As a very first pass, on most terminals you can crank an internal pot
to increase the maximum brightness. You will almost certainly find that
there's some interaction with the focus.
In *my* opinion, using my current price/performance/effort/time tradeoff
matrix, if tweaking the pot doesn't yield a satisfactory display, the
right thing to do is get a new CRT for the terminal. Open up an
issue of _Processor_ and you'll find dozens of places that sell
replacement CRT's for terminals of just about every make.
Why go the new CRT route? Yes, it's expensive, but if you're going to
be using the terminal into the future (and it'll be just as usable fifteen
years from now as it was when it was new) it's the right thing to do.
