A note on the 5751:

Sometimes a 5751 can be used in lieu of a 12AX7. Some folks (guitar guys typically) that have gear that come equipped with 12AX7's will sub a 5751. They do this specifically because it colors the sound and changes the way their amp performs, as they look for ways to "distort." This is a matter of taste as the 5751 is a lower gain tube than the 12AX7. If someone tells you to use a 5751 because they like it, make sure it's the same piece of gear. A lower gain tube can, depending on the circuit, operate perfectly. However, in some extreme cases, the lower gain can cause high distortion and in some cases not even work properly.

5751 tubes do not have a "sound" that is particular to that tube, any more than 12AX7's have a "sound". It depends on who made the 5751 and when, the operating condition of the tube, and the circuit it's going into. Any other assumptions or statements about the merits of that tube are silly.

Platinum grade - The best of the best. Lowest noise and microphony with the tightest triode balance we have available. This is typically 10% or tighter, but may be higher depending on available stock.

Gold grade - Low noise and microphonics with a triode balance typically between 15% and 20%, but may be higher depending on available stock.

Driver/Buffer grade - Lowest noise but not the lowest in microphony. Triode balance will be similar to Gold grade.
This grade is only suitable for use in the driver stage of an amplifier, or the output/buffer stage of a DAC or CD Player.

If you have a preamp or phonostage, you need at least Gold grade.
