RE:You are looking at tubes as a tone control device

which is perfectly fine. But, perhaps your search for a tube that gives "(for a full-bodied, warm and good Bass)", is an indication that something is amiss in your stereo system. I use 12at7 a lot as a driver tube for the "RH" style single ended amps. I just do not hear that big a difference between brands on my Altec 19 speakers. In the rh amps the Valvo e81cc seems to perform the best but that performance is in terms of subtleties like richer harmonics, better detail in high and low frequencies. A tube should pass the frequencies required in a linear manner and not skew it to affect the listener's perception. I am not saying that tube rolling is not worthwhile, en contrare, i do it all the time. But, i would think that any strong "new testing" 12at7 should be good in your preamp. And if the affect you seek is met, then maybe your old tube was just ready to be replaced.
