Comparing the mid-'50s long black-plate RCA 12AX7 (not the original that RCA first made in 1947) to the short gray-plate 7025: the long black-plate breaks up earlier, has thicker mids and lows, the short gray-plate 7025 has tighter lows, chimier upper-mids, and breaks up relatively later. I'm aware of these RCA 12AX7 types:

I learned that I liked experimenting with different preamp tubes within the 6 required--i.e. 2 in the very front middle that have some top end air, 2 in the next slots that must be a solid tube, and then 2 in the outer slots that are a bit more generic. Right now I'm running a pair of organ pulls in the 2 outermost slots.

45RPM@60Hz. Audiophile. Posts: 11. Location: East Coast. Joined: January 1, 2011. I have read a few posts stating the 5751 tube does not have for what it's worth a haze or slight grain that some 12AX7s have.
