Vacuum Tubes

Heater, for unipotential cathode. 117 volts AC-DC.

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

The 5Z4 is designed for service as a power rectifier in AC operated receivers.

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 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.

Glass-type half-wave high-vacuum rectifier with an indirectly heated cathode. It is especially designed for use in a-c/d-c and automobile receivers.

Full-wave rectifier of the heater-cathode type intended for use in AC operated and automobile receivers. Because of its heater-cathode construction it has the same heating time as that of other heater-cathode types in the receiver.

Isa full-wave high-vacuum rectifier designed for damper service in television deflection circuits. It can also be used in conventional rectifier applications.

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.

Ruggedized heater-cathode type double diode using the 9 pin miniature construction. It is suitable for use in half or full wave rectifier applications or as a voltage doubler.

The 6X5G is an indirectly heated full-wave rectifiers for use in equipment where the current drain does not exceed 70 mA.

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 as a full-power rectifier in television receivers.

New-Old-Stock (NOS) tube. The 35Z3 is a half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. Electrically the 35Z3 is equivalent to the 35Z5GT except that the heater of the 35Z3 is not tapped for operation of a panel lamp. The 35Z3 is a loctal-based tube (compared to the octal base of the 35Z5GT.)

Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment

Miniature heater-cathode type twin diode designed for full-wave rectifier operation in compact power supplies. The tube is intended for service in automobile and a-c radio receivers.

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.

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.

Power rectifier with low internal voltage drops. It is designed for service in AC operated receivers that require high currents

Full-wave rectifier

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.

Long life, ruggedized, reliable full wave rectifier tube.

High vacuum full wave rectifying tube.
