Ah right! No problem then. Well, as you know, you are looking at a
push-pull
amp with beefy tubes, and not paralleled. I personally wouldn't go above
350v
or so but if you're feeling hardy you'll get more watts. There's a number
of
posts on the asylum extolling 211 and 845 amps at lower voltages, but you
lose
the power. Have you heard the Nagra for starters? Is your system balanced
or
unbalanced?

Unbalanced via an ARC sp11 MkII pre but I could use the seperate inverted
output as well to makeup a balanced feed.. depending on if its truly
inverted (180 deg)
