starts with the finest tubes available from around the world. They then
test and match every tube, while under stress of actual operating
conditions, to the tightest, most demanding specs in the industry with
the use of their proprietary, aerospace designed tube analysis system
called Robotube. They accept only the finest of the finest and back
them with the best warranty in the business for a minimum of six months
King of the Tube Testers.
the brains of a computer and the ears of a
musician, Robotube runs a battery of seven exacting tests on each power
tube and analyzes performance so thoroughly it can even predict the
tube´s lifetime. Designed by Mesa Engineering and built by an
aerospace firm, Robotube is a one-of-a-kind machine and easily the most
modern and powerful in the industry.
data generated during the seven-part
test procedure is combined in Robotube's memory and later printed out
for each tube. But there are still some factors of tube performance
that only a human (with a hammer) can properly analyze. After passing
tests for noise and microphonics, then comes the severest mauling of
all the MESA hammer test. Here each tube is tested for reliability
under sever shock and vibration....enough to duplicate your
amp falling off a six foot stage at full volume!
the MESA guarantee: Six months under Heavy Duty use. That´s
twice as long as most. You can find tubes that cost more, but if they
worked any better, MESA would be using them!
