The JJ Electronic GZ34 / 5AR4 is rugged rectifier at a reasonable price. JJ has a reputation for building sturdy tubes and this one is no exception. Users report that the JJ GZ34 / 5AR4 is a reliable rectifier in their Vox, Fender, and hifi amplifiers.
The JJ Electronic 5Y3S is a ruggedly built octal rectifier tube with a directly heated cathode. This tube’s solid construction and thick glass envelope offer high reliability. The JJ 5Y3S will work in any 5Y3 position.
Octal rectifier tube (Max DC output current = 125 mA) An indirectly heated diode intended for rectification of commercial-frequency alternating current. It has a 140 mA maximum output and filament voltage of 5 V and a filament current of 2 A ± 0.2 mA.
Tube Amp Doctor 5AR4 Rectifier, Premium Selected. A faithful reproduction of the Mullard/VALVO GZ34. Pure power and the typical sag is the distinguishing characteristic of the most popular guitar amps of the 1960s guitar heroes till today.
The JJ Electronic 5U4GB is an excellent choice for an economically priced tube rectifier. Used in many Hi-Fi and guitar amplifiers, JJ delivers a robust and solidly built tube. This full wave rectifier will work in any 5U4 application.
The JJ Electronic EZ81 is a noval based rectifier with a rugged construction. These tubes are an excellent choice for guitar amps such as 18W Marshalls and Hi-Fi amplifiers as well. This tube will work in any EZ81 or 6CA4 application.
Chinese 5AR4 Vacuum Tube
5AR4 Ruby, Rectifier Tube
Solid State Rectifier Direct plug-in replacement for 5AR4, 5U4 and 5Y3 rectifier vacuum tubes in amplifiers with center tapped secondary power transformer. Use when less 'sag' is desired in the power supply; just switch back to the tube rectifier when 'sag' is desired.
Valve Art, 274B Rectifier Tube
Superior directly heated rectifier Diode. Replacement for all 5U4 types, including NOS-style "big bottle" tubes.
Octal rectifier tube (Max DC output current = 250 mA)
Miniature half-wave rectifier for use in line-operated equipment having series-connected heaters. The heater is tapped to permit operation of a panel lamp.
This full-wave, high-vacuum rectifier is specifically designed for aircraft, military, and industrial applications where freedom from early failures, long service life, and uniform operating characteristics are extremely important.
Cathode type rectifier designed particularly for use in automobile receivers.
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
Starting at $17.60
Half-wave rectifier in the 7 pin miniature construction. Features of the tube are a 100mA. heater with 20 second warm-up time.
Designed primarily for service as a power rectifier in ac-dc receivers. Two separate rectifier sections permit using the tube as a voltage doubler, full wave rectifier, or half wave rectifier.
Miniature full wave rectifier.
Miniature, heater-cathode, twin diode for full-wave rectifier operation. High output current and small size make it especially suitable for compact amplifier designs.
High vacuum rectifier intended for use in full-wave applications. The tube incorporates an indirectly heated cathode which is internally connected to the heater
Cathode type high vacuum rectifier designed for full-wave applications. The cathode is connected internally to the heater.
Starting at $11.65
The 5Z3 is designed for service as a power rectifier in AC operated receivers which require high currents
