The earliest Rackmount Rev F I have found is #829. Additionally, a rackmount version of the Dual Rectifier was now available for 1993 and came in black on black color config but could have a Chrome chassis for an additional $100. Rev F also saw the introduction of the all-new Triple Rectifier, the 150 watt behemoth that was so named not because it had three rectification modes but simply because it was a more powerful version of the 100 watt Dual Rectifier. The clean channel now used one side (or half) of each preamp tube position to create its Clean Channel, which brought with it improved dynamics, clarity and less grit. Revision F was a big change for the Rectifier circuit. This site will be continually updated as well. The information found here is based on years of research and direct conversations with folks at Mesa Boogie. The initials 'GM' are found on the vast majority of the 2 channel Rectifiers and these initials belong to George Mueller, with MB (Mike Bendinelli) also initialing off the builds. The Clean channels experienced the most changes and this would in turn affect the dirty channel to varying degrees. So why all the revisions? Well, Mesa Boogie were never shy about improvement to any of their amplifier circuits (ref: the Mark Series for example), and while internet forums and Facebook Groups love to talk about how different each Revision is, the truth is all of the various Revisions are pretty similar in the Gain channels. This site was created to help document the various revisions and changes that occurred from 1992 until late 1999/early 2000 when the three channel Rectifiers were released. Welcome to the Mesa Boogie Rectifier Guide for the 2 channel Dual & Triple Rectifiers.
