C'mon Maude.......... sigh.... . rejection........

Hello there, I actually was reading your old ad for the clear image audio t4 that recently sold.
I haven't found anyone else who owns us so I was wondering if I can ask you a few questions.

I just bought one of those used, no manual, and no original power cord.

Just wondered a couple things:

One, any power cord you would recommend? I know they came with Kimber.
Two, what exactly do the rocker switches in the back do? I know there are 3 positions, neutral in the middle, up, and down...

Any info would be greatly appreciated!

thanks
Steve
