I agree with those who point out that, generally speaking, preamp tubes will last for years, and that the CJ preamp you own is an anomaly or just cranky product design. There are a lot of fine tube preamps out there. I’m particularly fond of the 6SN7 tube for it’s open, natural and relaxed sound, as well as it’s sturdiness, longevity and relative affordability. A number of preamps are based around that tube, including the Black Ice Fusion F360, the Icon Audio Pure Valve, the Cary SLP-98 and the LTA MicroZOTL. Another option is a used Don Sachs Aikido preamp. I myself use my own version of the Aikido circuit, and it’s just a wonderful sound. I'm currently using Sylvania 6SN7WGT's in it. They weren't cheap, but I expect them to last four years or more before I need replacements.
But beyond the 6SN7, there are a lot of great and reliable tube preamps, some mentioned above. I’ve rarely encountered a tube preamp that "eats" tubes. I don’t see any reason to give up your preference for a tube preamp just because one particular model is giving you issues.
