Power Amplifier Pentode
The Sovtek EL84M Vacuum tube is a miniature type
used in the output stage of audio-frequency
amplifiers. They require a miniature 9-contact socket.
The EL84M is equivalent to the 7189 tube. It is the
military version of a normal 6BQ5 / EL84. It also has
more power and longer life than a 6BQ5 / EL84.
EL84M tubes have a cleaner sound and are harder to
distort and break up, making them great for audio or
stereo amplifiers. A lot of musicians prefer normal
EL84's for their guitar amps. They have a warmer
distortion and break up sooner than EL84M's. Now if you
want a cleaner sounding amp, then try the EL84M's.
EL84M's withstand higher plate currents than any New
Production or New Reissue EL84's.
If you want a good inexpensive stereo tube for your amp,
These will work nicely.
