[GreenKeys] Loop supplies or selector magnet drivers

[W9DDD]

Wonder what people are using these days loop supplies and keying the 
loop or selector magnet directly.  I was thinking of going old school 
with 120 VDC and a series 2,000 ohm 10 watt resistor. But, looking at 
the prices for 10 watt resistors, I'm re-thinking things.

I might get lucky with something already being in the LESU of the 
pending 28, but I'm not counting on it.  I'm trying to get setup so all 
I have to do is plug it in when the 28 arrives.
