Vacuum Tubes

High-vacuum rectifier intended for use as a full-power rectifier in television receivers.

Filament-type high-vacuum full-wave rectifier designed for service in power supplies of moderate current requirements. The electrical characteristics of the 5AZ4 are equivalent to those of the 5Y3GT.

New-Old-Stock (NOS) tube 5R4GA - Rectifier, Full Wave

Glass octal type for industrial and military applications.

The 5R4GY is designed for rectifier use in equipment requiring a high peak inverse voltage rating. Satisfactory operation of this tube type under conditions falling within area 1 on curve no 1 may be obtained without filament preheating.

Long life, ruggedized, reliable full wave rectifier tube.

The 5T4 is designed for service as a power rectifier in AC operated receivers.

The 5U4G is designed for service as a power rectifier in AC operated receivers which require high currents

The Psvane 5U4G is a directly-heated rectifier with an octal base. The Psvane 5U4G features the iconic shouldered bottle of the original 5U4G rectifiers. This tube is a great rectifier for any type of amplifier. The Psvane Classic Series is focused on the reproduction of popular vacuum tubes found in classic audio equipment. When designing the Classic Series, Psvane collected the most sought-after NOS tubes and analyzed each element of their construction, incorporating the most effective manufacturing techniques to produce stable tubes with excellent sound. Whether used in guitar amplifiers or hifi stereo systems, the Psvane Classic Series vacuum tubes excel in all applications. Psvane has been producing high quality vacuum tubes since 2011. The Psvane team originally formed in Shuguang’s high-end tube division but eventually split off to form their own brand.

Filamentary twin diode designed for use as a full-wave rectifier in the power supply of television receivers or other equipment which has high direct-current requirements. The 5U4GB may be used a replacement for either the 5U4G or the 5U4GA.

Superior directly heated rectifier Diode. Replacement for all 5U4 types, including NOS-style "big bottle" tubes.

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.

Cathode type high vacuum rectifier designed for full-wave applications. The cathode is connected internally to the heater.

High vacuum rectifier intended for use in full-wave applications. The tube incorporates an indirectly heated cathode which is internally connected to the heater

The 5X4 is designed for service as a power rectifier in AC operated receivers which require high currents

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.

Full-wave vacuum rectifier.

Filamentary twin-diode designed for full-wave rectifier operation in power supplies that have D-C output current requirements up to approximately 125 milliamperes.

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.

The Tube Amp Doctor 5Y3GT / 6087 is a small bottle rectifier designed to perform closely to the original rectifier tubes used in many 1950s tweed amplifiers. This rectifier offers high reliability due to its rugged construction and the Tube Amp Doctor Premium Selection process. The TAD 5Y3GT is a great tube for vintage style sag compression.

The 5Y4G is designed for use as a power rectifier in AC operated receivers.

Full-wave vacuum rectifier

Full-wave vacuum rectifier. The 5Y4GT is the same as the 5Y4GA except for mechanical design.

The 5Z3 is designed for service as a power rectifier in AC operated receivers which require high currents
