[Amps] Load testing HV power supplies

[Karl-Arne Markström]

When building a 2 x 4-1000A amplifier in the late 70's,
I load tested its 3-phase PS using 25 series connected 220 V 200 W 
light bulbs.

With a HV knife switch in series, actuated with a wooden broom shaft, 
the no-load/load characteristics
could be evaluated.

I am in the midst of making a couple of HV power supplies. I would
like to know if there's a safe means of testing these under load,
without using the RF deck and an expensive tube to put a load on?

One supply is hopefully going to give about 3800V DC at about .8 of 
an
Amp, the other about 5kV at about 1.8 Amps. I would also like to be
able to load a transformer's AC output itself up to see how it reacts
under load. Has anyone "done this at home" and lived to share the
story? :) Thanks.
