Mesa Boogie 5U4GB Rectifier Tube Single Model 750541F

Mesa Boogie 5U4GB Rectifier Tube: Essential Dynamics for High-Performance Amps

Enhance your amplifier's performance with the Mesa Boogie 5U4GB Rectifier Tube, the pinnacle choice for achieving traditional vintage sag and exceptional responsiveness. This rectifier tube is favored in the production of all new Mesa amps that utilize this component, renowned for its elastic and compressed feel, which is preferred among professional musicians for its dynamic response.

Traditional Vintage Sag with Modern Reliability

The Mesa 5U4GB tube is designed to produce a "traditional vintage sag," offering the most elastic and compressed feel of the two 5U4 models that Mesa offers. It provides an amazing playing feel that can make your notes sing with a warmth and clarity that enhances any musical performance. Based on classic 1950s technology, the 5U4GB has been re-engineered to exceed the reliability and consistency of the original designs while maintaining a compact and efficient form factor.

Compact and Carefully Designed

The 5U4GB tube boasts a shorter, more compact profile compared to the original Coke Bottle 5U4Gs, measuring just 3 3/4" from the bottom of the base to the top of the glass. Its size is similar to a 6L6 power tube, making it essential to ensure correct installation in the specified tube positions, especially when also replacing 6L6 tubes. This careful attention to detail ensures optimal performance and compatibility with your amp.

Unsurpassed Quality for Mesa Amplifiers

As with all Mesa tubes, the 5U4GB Rectifier Tube is selected for its premium grade quality, offering unsurpassed consistency and reliability. It's particularly used in iconic Mesa amps such as the Dual and Triple Rectifiers, Road King, Roadster, Stiletto Ace, Deuce, and Trident. These tubes are essential for maintaining the legendary tone and performance that Mesa Boogie is known for.
