VAX 4000-500 PSU Overload?

A bench test of the PSU with a small dummy load saw the PSU appear to work
fine. It might help to load it more to see if it still operates correctly
under load. The specs for the PSU are:

22 amperes at +12.1 Vdc
60 amperes at +5 Vdc
7 amperes at +3.4 Vdc
4 amperes at -12.1 Vdc

Has anyone got any suggestions for how to create a higher load in a fairly
simple manner? It would take a lot of resistors or vehicle light bulbs to
create some of those loads, and something heftier than a breadboard to
connect them together.
