Whoa, there's the single getter Mullards. Whether they are xf2s I can't tell but I would bet so. The preamp tube chart is a puzzle perhaps implying American and Euro, but it really makes no sense to consider a Holland Amperex or Mullard 12AX7 not up to the 7025 rating. Definitely no Tungsram and it's dated 2002. Hm. I'm thinking this is some Kenny misdirection but I would be willing to learn otherwise.
Anyway, thanks for the pics!
Most people stall out when fixing a mistake that they've made. Why?
I don't know the history behind this amp, though it's a lot of money for history, it would be cheaper to make history!
$55K WOW!
I'm surprised Keith Urban owns it, it's not your typical country amp. I read the Vintage Guitar article where John Mayer asks K.U. what he pays for his guitars and says why not pay similar money for amps. I dare say Nancy wasn't his sort of amp.
