Where to find data sheets?

I've been looking around, after much consideration, and I think my first amplifier project is going to use either the Tung Sol 6550 or EH KT-88. However, I have not had much luck finding a real data sheet for either of these tubes.

Isn't there enough change between manufacturers that one would want the actual mfr. data sheet? Can anyone maybe point me in the right direction?

Right now I've considered the TubeLab SimpleSE as well as trying to roll my own design. Even if I don't try building from scratch first, I'd still be interested in running through the steps.

Any comments on these two tubes is also welcome. The TS is the new Russian version, as the NOS is a bit more than my budget can take right now.

Thanks!
