sovtek el84 vs el84 M

[Loggie]

friends I don't know if is the just section.
but whats the differences between this 2 type of tubes?

[mattumbi]

M is the military version, stouter construction and more expensive. I believe the standard version is generally preferred for tone in git amps. But the M can hold up better in amps that really run the output tubes hard. Never tried the M version myself but have usually been happy w/the standard sovtek el84.

EH's EL84's are Sovtek's and seem to be quite decent valves, for £8 a piece
