I first used these on my Melody tube integrated. Real effective, about equivalent to a pretty decent power cord. Same on my Herron phono stage, which uses tubes and is about equivalent to a preamp in terms of current draw.
Speaking of which, why you need 10 AWG on a preamp? First, AWG is gauge not amps, 10AWG would be solid core wire not a fuse. And if you mean 10A, that is an awful lot for a preamp. My Melody only uses 8A and it is a 50W power amp!
