You might pay a bit more going to retalier butwon't have towrroy about time on tubes or whether or not it's a fake by calling Kevin Deal at Upscale Audio.He might have some old new stock like french Mazda or something other than Telefunken or Mullard.Recitfiers/inputs is what I have done for a few amps in NOS because of longer life but a popular output tube like an EL34 (I still miss my CJ that ran them) was cost prohibitve with me.Might email Cary as well as Manufaturers have certain ones they reccomend.Bel Canton told me to get a 12ax7 that was as specific (CCA Thunderbird) if I was going to use NOS so they might put in worthwhile 2 cents.But Deal has helped a buddy of mine in California and treated him right on return trips with prefference pricing.
