He's not named anything - it's my own understanding that most tube pre's are starved plate. Is that not right?
As far as I know The Walkabout, MPULSE 600, Warwick Tubepath and the R400 are full voltage, and from memory I like the way they break up compared to, say, the SS Ampegs and Class D's I've owned previously.
I'm genuinely happy to be edumacated otherwise, though...?
