Vacuum Tubes

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 811A Available in Singles or Matched Pairs - please select from list.

Miniature beam-power pentode designed for use in the audio-frequency power output stage of television and radio receivers. It may also be used as a triode-connected vertical deflection amplifier in television receivers.

Superior medium-mu twin triode driver tube for hifi use. 3.5 watts dissipation per plate. New design of excellent quality

Higher in gain than the 5881WXT, with full base.
Sovtek is proud to announce the release of their new 6L6WXT+ vacuum tube. Modelled after the vintage RCA 6L6GC "blackplate," the Sovtek 6L6WXT+ features larger plate dimensions and improved grid structure for increased power handling capabilities. The 6L6WXT+ also features mica spacers with metal springs to eliminate tube rattle and microphonics. The Sovtek 6L6WXT+ yields a 20% higher output than the Sovtek 5881WXT and offers superior tone and overall performance to any 6L6 or KT66.

Copy of the original type 3 Tung-Sol 6550 made in the 1960s. Triple getter, carbonized screen, and gold plated grid. The current production benchmark of the classic 6550.
Made in Saratov, Russia

Miniature heptode primarily designed to perform the combined functions of the mixer and oscillator in superheterodyne circuits in both the standard broadcast and FM bands.

Octal power tube (Max Plate Watts = 30W)

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.

The T-12SK7 is the same as the 6SK7 except for heater ratings.

Beam pentode primarily designed for use in the audio frequency power output stage of radio receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.

The 6AL5 combines two independent diode units in the 7 pin miniature construction. Its high perveance permits high efficiency in either FM or AM detector service.

The 6K6GT is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.

Tube measurements are as follows:

• Height: 2.75” (without pins)*
• Diameter: 0.87” *

*Note: Due to the method of production in regards to the glass, measurements may vary slightly.

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.

Sovtek 6SL7GT

Chinese 6V6GT Available in Singles, Matched Pairs or Matched Quads - please select from list.

Metal sharp-cutoff pentode designed for use as a biased detector or high-gain amplifier.

Pentagrid converter designed to minimize frequency drift. They are intended for service as combined oscillators and mixers in AC, storage battery, and AC/DC operated superheterodynes.

7591A Electro-Harmonix Power Tube Beam power tetrode used in vintage Ampeg and Gibson guitar amplifiers. Also, used in tube hi-fi equipment made by Fisher, Scott, and Harmon-Kardon.

Remote-cutoff pentode. It is designed for use as a high-gain radio-frequency or intermediate-frequency amplifier in a radio receiver.

Miniature remote-cutoff pentode designed for use as a radio-frequency or intermediate frequency amplifier in compact, battery-operated equipment.
