First of all, this not an attack on NOS tubes …

A very strange introduction. Since when people post at this site feel a need to ask apologies for attack or not attack anything? Also, where this phase “attack” ever came from?  Adrian I can assure you that people who find useful for them to visit this site, not to say post here, have no personal spiritual investment into any agenda. So, would you attack the NOS tubes or not attack them it recognize as nothing else them your assessment of NOS tubes. If people feel that you “attack” the NOS tubes then the people are idiots and who care what they feel. I do not know many idiots in audio who feel that expressing a justified criticism is a personal attack. I have seen intense cases when people go to extremes, whoring own wife and losing all dignity and respect to truthfulness/really just because somebody express a skepticism toward to their sound (like that dirt from the PA’s Mill). I true hope that those attitude are not reveling in this site and there is no need to remind  that your objectives are not “to attack”.

Again, it is just a my own test in my own circuit with a few listeners. I would say that my impressions of other types of tubes generally coincide with the many stated on various forums, so I do not think my set-up is abnormal in any way; it is a real-life application for 2A3 tubes and I expect any 2A3 I buy to function in it.

Well, it is not a conversation about your set-up “being abnormal in any way” but about evolution methods. It you replace your 6SN7 with other vintage then it would be not a big deal and the result will be demonstrate the difference in the tube. Even if you run twice more current over your driver tube it will not affect sound a lot. The output tube and partially in no feedback amp is a different story. Some NOS and the new tubes are so different then need to be used differently in order to have own best respectful applications. I just say the it is very difficult subject and juts puling the tubes in and out is NOT always send the very different tubes in identical operation environment.
