I've never heard this amp but if you're spending over 3k I'd definitely splash out 300 bucks for a pair of Amperex 7316s. The 12au7s will be voicing your amp to a large degree so they're really important. Maybe try some cheap German RFTs and not so cheap Mazda silver plates if the Amperex don't work out. Hard to know how they'll sound in your amp. Hmm. I'd disregard my advice until you hear from another owner if I was you. What are the stock tubes?
