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.
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.
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.
Heater-cathode type diode designed for use as a half-wave rectifier in ac/dc receivers. A heater tap is provided to permit operation with a panel lamp.
In the 12DW7/ECC832, Section 1 of the tube (pins 6, 7, and 8) is the high gain 12AX7/ECC83 spec (gain factor 100) and Section 2 (pins 1, 2, and 3) is the low gain 12AU7/ECC82 spec (gain factor 17).
Starting at $12.95
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.
Combines two diode units and a high-mu triode in a single envelope. Each section uses a common cathode. It is intended for service as a combined detector, AVC source, and high gain audio amplifier.
Octal rectifier tube (Max DC output current = 250 mA)
Superior directly heated rectifier Diode. Replacement for all 5U4 types, including NOS-style "big bottle" tubes.
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.
Combines a high mu triode and two independent diode units in the 7-pin miniature construction. It permits a single tube to function as detector, AVC rectifier, and audio amplifier.
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.
Package of 2Chinese 811A Available in Singles or Matched Pairs - please select from list.

Miniature duplex-diode, high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor
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.
Medium mu triode and a sharp cutoff pentode. The pentode section may be used as an IF amplifier or a reactance tube; the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits.
Cathode type rectifier designed particularly for use in automobile receivers.
Miniature, medium-mu triode suitable for use in a wide variety of general purpose applications. It is especially useful as a local oscillator in high-frequency and very-high-frequency receiver circuits.
Filamentary twin-diode designed for full-wave rectifier operation in power supplies that have d-c output current requirements up to approximately 125 milliamperes.
Premium directly heated heavy duty rectifier Diode. Re-issue of the most popular rectifier valve ever built by Mullard. Helps extend the life of the other valves in the amplifier by allowing them to heat up before plate voltage is applied.
- Low internal voltage drop & controlled heater warm up time
- Excellent choice for both Hifi and instrument amplification
- Replacement/upgrade for all 5AR4/GZ34 types
Metal duplex-diode high-mu triode. It is intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers.
5AR4 Ruby, Rectifier Tube
General-purpose triode designed for use as a detector, amplifier, or oscillator. Features include a relatively high transconductance and a medium amplification factor.
