Mesa Boogie EL-84 (6BQ5) Matched Tube Duet
Item: MB750604D
Mesa tubes are hand selected, matched pairs that are matched by a sophisticated high-tech analyzer, then actually screened by a listening test to weed out microphonic and noisy tubes. When you buy Mesa tubes, you are getting tubes that are exactly biased to your amp and are of the highest, most reliable quality. This is a matched EL84 pair.
