Mesa Boogie Replacement Tube Set For Dual Rectifier
Available Now at Northeast Music Center!
Bring the massive power, tight response, and unmistakable authority of your MESA/Boogie Triple Rectifier back to full strength with a complete factory-style replacement tube set. Featuring six MESA 6L6 power tubes, five MESA 12AX7 preamp tubes, and three MESA 5U4 rectifier tubes, this complete retube configuration provides the full standard tube complement required by the legendary Triple Rectifier Solo Head.
The MESA/Boogie Triple Rectifier is one of the most formidable amplifiers MESA has ever produced.
With up to 150 watts of Class A/B power, six power tubes, three rectifier tubes, three channels, and the enormous low-end authority that helped define the Rectifier sound, the Triple Rectifier was built for players who demand serious performance.
An amplifier like this depends heavily on the condition of the tubes inside it.
Available from Northeast Music Center, this complete replacement tube package gives Triple Rectifier owners a straightforward way to refresh the entire standard tube complement.
• 6 × MESA 6L6 Power Tubes
• 5 × MESA 12AX7 Preamp Tubes
• 3 × MESA 5U4 Rectifier Tubes
• 14 tubes total
• Standard factory-style 6L6 configuration
• Designed for compatible MESA/Boogie Triple Rectifier Solo Head amplifiers
The Triple Rectifier uses:
6 × MESA 6L6 power tubes
in its standard configuration.
Six power tubes are a major part of what gives the Triple Rectifier its name—and its enormous authority.
These tubes contribute to the amplifier's:
Massive headroom
Powerful low end
Aggressive attack
Dynamic range
High-volume stability
and the physical response that separates a 150-watt Triple Rectifier from smaller amplifiers.
When the power tubes become tired, the amplifier may begin to lose some of that authority.
Low frequencies can become less controlled.
Attack may soften.
Clean headroom can decrease.
The amplifier may feel less immediate.
A fresh properly matched power-tube set can help restore the response a Triple Rectifier is supposed to have.
The Triple Rectifier also uses:
5 × MESA 12AX7 preamp tubes.
These tubes are responsible for critical stages throughout the amplifier, including input and gain stages, the effects loop, and phase-inverter/output functions.
The Rectifier preamp is capable of everything from clean sounds to some of the most recognizable high-gain guitar tones ever created.
Healthy preamp tubes help preserve:
Gain structure
Clarity
Definition
Harmonic complexity
Low noise
and:
Consistent channel performance.
This is the part of the Triple Rectifier tube set that shouldn't be overlooked.
The amplifier uses:
3 × MESA 5U4 rectifier tubes.
These are part of the amplifier's selectable tube-rectification system and contribute directly to the feel and response associated with the Rectifier design.
Tube rectification can produce a softer, more elastic response with greater compression and sag.
Silicon-diode rectification produces a tighter, faster, more immediate response.
Having healthy rectifier tubes ensures the amplifier can deliver the tube-rectified behavior it was designed to provide.
The Triple Rectifier uses MESA's:
Maintenance-Free Fixed Bias
design along with the 6L6/EL34 Bias Select switch.
When using properly selected MESA tubes and the correct Bias Select position, the amplifier is designed to operate within its intended bias range without the conventional adjustable-bias procedure required by many other tube amplifiers.
That makes future tube maintenance considerably more straightforward.
Tube wear often happens slowly.
A Triple Rectifier may continue functioning while gradually losing some of the qualities that made it exciting in the first place.
You might notice:
Less low-end authority
Reduced clean headroom
Softer attack
More noise
Microphonic preamp tubes
Reduced gain definition
Inconsistent performance
or:
A general loss of punch and immediacy.
A complete retube gives you the opportunity to refresh the entire amplification chain rather than replacing individual tubes one at a time as they fail.
