Vacuum Tubes

Miniature, medium-mu, twin triode primarily designed for service in computer applications. Each triode section features a high zero-bias plate current, a sharp-cutoff characteristic, and a separate cathode connection.

Electro-Harmonix 6CA4 full-wave rectifier tube. Made in Russia.

Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. The 50A5 features high power sensitivity and high efficiency when operated at relatively low plate and screen voltages.

Beam power pentode intended for service as an audio power amplifier.

The Psvane KT88 is a high quality, high power, beam tetrode with an octal base. The KT88C is notable for its warmth and clarity across the entire audio spectrum. 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. Psvane has since acquired their own manufacturing facilities with the goal of improving the production and performance of vacuum tubes.

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

Low voltage, low current drain battery type beam power output tube. It is designed for services with 90 volts of "B" battery and a single dry cell "A" battery.

Compactron containing three high-mu triodes. It is designed for use primarily as a color-difference amplifier in color television receivers.

Genalex Gold Lion PX300B power triode tube with gold pins. Made in Russia. In Europe during the 1930s the GEC (Genalex)/Marconi-Osram PX4 and PX25 power triodes were considered the finest audio triodes of their day. In keeping with the tradition of Genalex to provide the highest quality tubes, New Sensor has released the Genalex Gold Lion PX300B audio power triode. This tube is the highest quality 300B type available and is considered to be an upgrade in any 300B amplifier.

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.

Compactron beam power pentode designed for use as the horizontal deflection amplifier in television receivers.

Triple grid variable MU amplifier. It is suitable for use with AVC in RF and IF amplifiers as it minimizes cross modulation

General purpose triode designed for service as an oscillator, detector, or amplifier. Except for heater voltage and current its characteristics are identical with those of the 56.

9-pin miniature type high-mu twin triode, with heater having controlled warm-up time.

Heater-cathode type high-mu triode designed for service as a high gain audio-frequency amplifier and is especially useful in resistance-coupled amplifier circuits in a-c or battery operated equipment

Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.

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

Mullard 12AT7 / ECC81 dual triode preamp tube. Made in Russia.

Filament type power-amplifier pentode tube designed for use in the output stage of battery operated equipment.

Miniature, heater-cathode, twin diode for full-wave rectifier operation. High output current and small size make it especially suitable for compact amplifier designs.

Large black plastic control knob with set screw and brass insert. This distinctive pointer knob is similar to the selector knobs used on original MiniMoog and Moog modular synths. It features a triangular pointer, a radial brushed metal top, and a line indicator. The large skirt has a diameter of 1.125 inches. Fits ¼” (6.35mm) pot shafts.

High-mu power output triode designed for service in dynamic coupled circuits using a type 76, 6P5GT/G or 6J5GT/G as a driver. Two 6AC5GTs may be used as a zero bias class B amplifier.

Sharp cut-off amplifier pentode designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. The 6SH7 is not recommended for use as a high-gain audio amplifier because undesirable hum may be encountered.

Sharp cutoff pentode of the 7 pin miniature type with heater having controlled warm-up time.
