We recently came across a really nice collection of RCA 12AX7 Black Plates.
Vintage tube prices keep rising as supply continues to shrink — but every now and then we get lucky and uncover the right stash.

Did you know? The type of “plate” in your vacuum tube can determine your amplifier’s tone and performance. Although it may seem like something to ignore, plates can govern things such as quietness, bass & treble range, longevity, and tonal quality...

With vintage Marshall amps, the two most important tonal qualities are the strong mid-range and the high gain. This is in contrast with classic American-style amps (like Fender), which traditionally are heavy in bass and treble. You may want to consider tubes that have the desired tonal characteristics of the classic Marshall sound.
