Anybody tube rolled 845's?

I have the same exact amps as you do. Wonderful sounding amps. I installed a set of new production Cetron 845s and a set of new production Western Electric 300B and never looked back. When I first got the amps I bought the SuperTNT 845s but had so many tube failures that I finally gave up and went to the standard bearer. Would I love to have a set of NOS RCA 845s? You bet. Like you said the 211s take 4 so finding four matched RCA NOS 845s that don't end up costing $1000 per tube seemed impossible so I went with the Cetron. I am very happy I did. I never tried the KR. I stopped once I bought the Cetron.

Thank you for your response, Jaiello. Could you please tell me what the sonic difference was between the stock Chinese valves and the Cetrons?

I have the Cary 211AE also. Like you I was curious about the RCA 845s and eventually was lucky enough to find four. The Chinese 845s are great for the money but they sound flat, bright and sterile vs the RCA. The RCA 845s are more 3D, throw a bigger soundstage, life-like midrange, silky treble.
I dont use the RCAs everyday though, only on special occasions. I plan to have the RCAs for my retirement in thirty years. For daily listening the Chinese 845s will do. At this time, you probably wont find four RCA 845s. I would try the Cetron or GE just so you know what they sound like. They do take your amps to another level. Have fun.

If you go with the Chinese tubes..I recommend the Shuguang 845B. Its warmer than the metal plates (845C) and about 90% of their transparency IMO, and less expensive. A very good sounding tube. I agree with Nickt in that they are good enough to listen to on an everyday basis. Super TNT tubes are seemingly sold out till next year, according to their TNT site.
