Its classic tall coke-bottle construction delivers a softer power-supply response than a solid-state rectifier while remaining slightly more controlled than a 5U4GB.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis full-wave rectifier uses a directly heated 5-volt filament and an octal-style base. Under typical load it produces the gentle voltage drop that gives notes a responsive sense of give, making it well suited to amplifiers designed around vintage rectifier behaviour. Because the glass envelope is approximately five to five-and-a-half inches tall, available chassis-to-cabinet clearance should be confirmed before installation.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Type:\u003c\/strong\u003e Full-Wave Vacuum Rectifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeater Voltage:\u003c\/strong\u003e 5.0 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeater Current:\u003c\/strong\u003e 3.0 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plate Voltage:\u003c\/strong\u003e 450 V RMS per plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeak Inverse Plate Voltage:\u003c\/strong\u003e 1550 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Output Current:\u003c\/strong\u003e Approximately 225–275 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTypical Voltage Drop:\u003c\/strong\u003e Approximately 40–50 V at 225 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlate Resistance:\u003c\/strong\u003e 75 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase:\u003c\/strong\u003e Octal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBulb Style:\u003c\/strong\u003e Tall Coke-Bottle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate Height:\u003c\/strong\u003e 5–5.5\"\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eWhy you should choose the Mesa Boogie 5U4G Rectifier Amplifier Tube\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eChoose this 5U4G when the goal is a classic, touch-sensitive rectifier feel with a little more control than the softer 5U4GB response.
