Vacuum Tubes

Octal power tube (Max Plate Watts = 42W)

Genalex Gold Lion 6V6GT / CV511 beam-power tube. Made in Russia.

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.

The Tube Amp Doctor 6550A-STR is built and performs to the same standards as the highly sought after GE 6550A. TAD has meticulously designed the plate material to be as strong and pure as possible resulting in an exceptionally stable, consistent, and reliable 6550. The TAD 6550A features a thick straight glass envelope, a metal base, and an authentic triple getter. The frequency response of this tube is remarkably balanced and smooth. Transparent natural lows and thick rich mids with silky highs make this an excellent tube for HiFi equipment as well as classic bass guitar amplifiers. The Tube Amp Doctor 6550A-STR offers outstanding performance in all applications. This tube is matched for both plate current and transconductance. The TAD 6550A-STR also passes all of the tests required in the Premium Selection process.

Philips ECG, Triode, Medium-MU

Octal power tube (Max Plate Watts = 42W).

9 pin miniature preamp tube (Amplification Factor = 60)
Durable phase splitter or driver tube. Excellent in vibrato or reverb circuits where consistent, high output power is desired.

Metal pentagrid converter. It is intended to perform the combined functions of the mixer and oscillator in superheterodyne receivers, especially those of the all-wave type. The 6SA7 is constructed to provide excellent frequency stability.

High grade tube. Tweed Up Your Amp! Vintage tone for original vintage Fender tweed amps. The original tube for all those Fender® tweed amps from the 50s. Brings back the original sound to your tweed amp.

Miniature diode sharp-cutoff pentode designed for use as a combined detector, audio-frequency amplifier, and automatic-volume-control tube in compact, battery-operated receivers.

Superior power beam tetrode, engineered for demanding high fidelity, reliability and overall warmth. Traditional brown base.

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

Miniature pentagrid-converter designed for use as a combined mixer and oscillator in superheterodyne circuits. Because of its small size and high operating efficiency, the 1R5 is especially adapted for compact, battery-operated equipment.

General-purpose triode designed for use as a detector, amplifier, or oscillator. Features include a relatively high transconductance and a medium amplification factor.

0A2 or 150C2 - Voltage Regulator, Diode, miniature glow-discharge type.

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

KT88 power tube reissue of Genalex Gold Lion. Made in Russia.
In 1957 Marconi-Osram Valve Co. (Genalex) introduced the "King of Power Tubes", the legendary Gold Lion KT88. This tube became the heart and soul of such classics as the Dynaco Mark III, McIntosh MC275, and Marshall Major. Unfortunately, Genalex ceased tube production in the early 1980s and the Genalex Gold Lion KT88 has become very expensive and hard to find.
After extensive research and engineering, New Sensor Corp. has reissued the famed Genalex Gold Lion KT88.

Miniature power amplifier pentode designed for use in the power output stage of compact, battery operated equipment. It is particularly useful in three-way portable receivers which employ 90-volta batteries.

Blue glass envelope. The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.

Miniature tube containing three high-perveance diodes and a high-mu triode in the same envelope. One of the diodes has a separate cathode connection. The tube is designed for use as a combined AM and FM detector and audio-frequency amplifier.

Miniature, remote-cutoff pentode designed primarily for use as a high-gain radio-frequency or intermediate-frequency amplifier. Features include low grid-plate capacitance, relatively high transconductance, and low heater current.

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.

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

The 0C3-A is a two-element gas filled, cold cathode voltage regulator. It is designed to provide a regulated output of approximately 105 volts.
