There is no one pristine Tech print out there that we know of; not even a rumored one. The print which showed up at the Senator Theater, for example, is about a C to C+ at best, having a lot of platter damage and a somewhat dodgy Reel 6, though people think that looks great. There are far better ones out there. And, if you were able to acquire multiple Tech prints of superior quality to the Senator, you could probably get about as close to definitive as is likely to be gotten...
