Wow great information, as of now I am using the 1033 to power a postwar 681 and occasionally swap it out for a Santa Fe 2343. The loop is pretty standard in it that it is about 4 x6 and no accessories hooked up to it.
As I mentioned in another post I picked up a Century Club Niagara, but do not plan on ever running it on the 1033, even though my Niagara is a learning model (experimenting with learning how to work/repair new equipment.)
