If it seems like you are not too far away from having adequately high gain and adequately low noise, changing the 12AX7's in the TEA2 to tubes that have been carefully selected by a reputable vendor to have particularly low noise might get you there. Doing that with the tube(s) in the TEA2's input stage would have the greatest likelihood of being beneficial.
Otherwise you could insert a suitably chosen step-up transformer between the turntable and the input to the TEA2, although that would involve significant additional expense. Also, although I'm not sure how much significance this might have, if any, doing that would seem to go against the design philosophy of the TEA2. Based on reviews I've seen it intentionally avoids using a transformer at its input, thereby possibly improving its sonics with higher output cartridges but making it unsuitable, or perhaps marginally suitable, for use with cartridges such as yours that have particularly low outputs.
Bob's Devices offers moving coil stepup transformers that have received a lot of favorable comments here and elsewhere, and cost considerably less than a lot of the competition. He is a member here at Audiogon, btw, screen-name "Bobsdevices."
BTW, although phono stage noise specs tend to be inconsistently and incompletely defined and therefore need to be taken with several grains of salt, given the TEA2's hum and noise spec of "80 db below 10 mv input," and its specified 55 db of gain, and the 0.28 mv rating of your cartridge, I'm not surprised that there is a problem.
Hope that helps,
