Best suitable 845 Tubes for NAF 845 SE

I am using New Audio Frontiers 845 SE, even they sound good smooth BUT I am sick and tired of facing blowing Sophia Tubes after every 6 to 8 months. I had free replacement from them for more than 3 times, but I am really really tired. I am seeking for permanent solution.

I really can use a good advise of which 845 tubes available in the market are MOST suitable for NAF 845 SE for most permanent solution.

Thank you for your kind help in advanced,
Most sincere regards

The most reliable current production 845 tube is the Shuguang 845B. It sounds good, it handles the highest B+ voltage circuits and lasts. I have a seven years old pair in my Audion Black Shadow monoblocks and they still test well. You may find some sonic advantages to some of the more exotic alternatives, but I haven't found any of them to be as dead-reliable as the 845B. Another good alternative for a somewhat more aggressive sound is the cryogenic-treated 845A sold by ATSI.

Either of them drops into a standard RCA-spec 845 SET circuit.
