If you can't find an old linear wall wart in the 0.5-1A range, it may 
still be possible to find one at industrial electronics distributors. I 
bought several 2-3A 12V and 2A 24V supplies to run some custom LED 
lighting fixtures several years ago. They were not easy to find, and may 
being phased out. It's worth poking around online with those distributors.

I long ago standardized on the same Power Pole connectors that Elecraft 
used beginning with their earliest rigs, and run all the 12V gear in my 
shack and in my home from 12V batteries, float-charged from a suitable 
linear supply.
