Vacuum Tubes

Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier

In the ECC823, Section 1 of the tube (pins 6, 7, and 8) is the low gain 12AU7/ECC82 spec (gain factor 17) and Section 2 (pins 1, 2, and 3) is the high gain 12AX7/ECC83 spec (gain factor 100).

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.

Variable mu pentode amplifier in the octal metal (glass) construction. It is suitable for use with AVC in RF and IF amplifiers and minimizes cross modulation.

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

Medium-mu twin triode 9-pin miniature type, intended for applications where dependable performance under shock and vibration is paramount. The 5814A is a "premium" version of the 12AU7.

Miniature tube which contains a sharp-cutoff pentode and a triode in one envelope. Each section has a separate cathode and is electrically independent. Primarily intended as a combined triode oscillator and pentode mixer in television receivers.

Pentode amplifier designed for application in power output stages of receivers

Electro-Harmonix 6973 Power Tube Beam power amplifier used in vintage Gretsch and Magnatone amplifiers. This is a real 6973, not a rebrand of a "close" tube.

Russian Tung-Sol 6EU7 tube. High-Mu twin triode with 9 pin miniature base. Made in Russia.

Miniature 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.

Medium mu triode and sharp cutoff pentode in the 9 pin miniature construction. It is intended for use as a combined VHF oscillator and mixer in television receivers.

The 0C2 is a cold cathode, gas-filled diode of miniature construction designed for use as a voltage regulator.

Superior high-power Octal Beam Tetrode, suitable for any amp using 6550 or KT88. Designed to hold up in even the most punishing environment of high powered bass amps, such as Ampeg SVT. With 42 watts of plate dissipation in tetrode operation and 44 watts in triode, power is improved even over desirable vintage types.

Cathode type rectifier designed particularly for use in automobile receivers.

The Tube Amp Doctor KT-66 is an incredible remake of the classic British tube. With its large glass envelope contoured by smooth curves tapering into a rounded brown base, the TAD KT-66 not only looks like the original, it performs like the original. This KT66 offers plenty of headroom for a thick full bodied sound with smooth yet articulate highs. The KT-66 is famously used in vintage British plexi amps and makes a great replacement for that style of amplifier and many others. The TAD KT66 is matched for both plate current and transconductance and passes all of the tests of the TAD Premium Selection process. The TAD KT-66 can be used in any KT-66 position as well as 6L6GC and 5881 amps that can supply the required 1.27A for the heater.

Miniature, duplex-diode, high-mu triode designed for use as a combined detector, amplifier, and automatic-volume-control tube

The 3A5 is intended for use in high frequency applications. The relatively large filament employed in the 3A5 enables it to supply the high peak currents required in RF power applications.

Miniature pentode designed for use as a radio-frequency or intermediate-frequency amplifier in television receivers. Features of the tube include high transconductance and low interelectrode capacitances.

The Psvane 6SN7GT is a high quality, medium gain, dual triode with an octal base. The Psvane 6SN7GT is an excellent preamp tube with a classic look and sound. The Psvane 6SN7GT works great in any 6SN7 position. 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.

The JJ Electronic ECC99 is a noval based dual triode. This tube features a rugged construction and is also available with gold pins. The ECC99 is typically used as a driver for power triodes in 2A3 and 300B amplifiers but can also be used as a power tube in small amps and headphone amps. This tube can also be a functional replacement for 5687, E182CC, 6840, and 6BL7 tubes. Note: Sockets on some of these types could have a different set-up.

The 50L6GT is designed for service in the output stage of ac/dc receivers. It delivers a high power output with high power sensitivity from low supply voltages.

Electro-Harmonix 6CA7 Vacuum Tube Big bottle beam-tetrode version of EL34. Perfect EL34 replacement for Musicman amplifiers.

Mullard 6V6GT tube. Made in Russia. This valve is built to stand the high voltages encountered in the Fender Deluxe Reverb and other guitar amplifiers that ran the valves above the published specification. The smooth and balanced frequency response also makes it suitable for hi-fi use.
