Vacuum Tubes

The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
Vacuum Tube - 6V6, Double Mica, JJ Electronics
A custom version of the JJ 6V6-S with a double top mica for increased stability. The double mica improves support for the tube structure and reduces mechanical vibrations in its components. These double mica 6V6 tubes are a great option for combo amps and any amplifiers exposed to speaker vibrations. The JJ Electronic 6V6S is another modern classic from JJ. This 6V6 has the standard rugged construction we’ve come to expect from JJ which allows it to handle much higher plate voltages than the typical 6V6 tube. The JJ 6V6 can even be used in place of a 6L6 in some amplifiers. Overall this tube has a warm and balanced tone with incredible separation and response. The highs come in clean and smooth with a lot of clarity. The mids are full and distinctive. The lows are fat and punchy. These tubes can cover a spectrum of sounds and styles all within the same amplifier.

Resistor - W20 Series, Welwyn, 7 Watt, Wirewound
High quality W22 resistors from Welwyn / TT Electronics W20 Series. These 7W wirewound resistors are a great choice for screen grid and cathode bias resistors in tube amplifiers. The brown enamel coating used by Welyn looks great in vintage and vintage-style amps. These resistors can be found in many vintage Marshall amplifiers. A high purity ceramic substrate is assembled with interference fit end caps to which are welded the termination wires.

Vacuum Tube - 12AX7 / ECC83-WA, Tube Amp Doctor, Premium Selected
The new Tube Amp Doctor premium selected 12AX7 /ECC83-WA is a low-noise and low microphonic version of the 12AX7. The ECC83-WA Premium Selected has a balanced tone with a notable emphasis of the mids. The overall linear sound offers great string attack and chord separation. The low end is well defined. The result is a tone that works well in both modern amps but also vintage guitar amplifiers. If the ECC83-WA is used in hi-fi audio amplifiers, the tube adds a musical clarity and presence to the signal. The new TAD™ ECC83-WA is a miniature, high-mu twin triode, selected and recommended for guitar amps to improve overall responsiveness and dynamics. Great for guitar clean tones with a distinct pick attack and pronounced upper mids to cut through every mix. Crunchy tones still feature a very good string separation which is also ideal for fully saturated sounds and modern amplifiers with a tight bass response.

Vacuum Tube - KT88-STR, Redbase, Tube Amp Doctor
The TAD KT88-STR Redbase® is built in the style of the early British MOV KT88 with the big and heavy glass envelope and beautifully polished metal base. The Redbase® features a gold control grid for outstanding performance and reliable stability. A breath-takingly big and precise tone and great appearance make the new TAD KT88-STR Redbase® the best choice for both, high-end audio applications and powerful bass guitar amps, providing a natural and three dimensional tone with pleasingly full warmth and fine, subtle highs. A very musical response, with great sound and finest details in mids and top-end; a linear and harmonious overall response with a very organic tone, make the TAD KT88-STR Redbase® TAD’s favorite tube in the KT88 and 6550A class.
Starting at $67.50
Vacuum Tube - 2A3, JJ Electronics
The JJ Electronic 2A3 features a robust construction in a beautiful thick glass envelope. The JJ 2A3 offers 40 Watts of plate dissipation which far surpasses the headroom of other 2A3 tubes by 25 Watts. The single plate build and increased ratings give this tube the highest reliability. The JJ 2A3 has amazing detail and clarity with excellent separation.

Vacuum Tube - KT88, Genalex Gold Lion
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.
