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 - 6L6WXT+, Sovtek
Higher in gain than the 5881WXT, with full base. 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. The ultimate 6L6, the WXT+ will improve the sound of any 6L6 guitar amplifier.

Vacuum Tube - EL84 / 6BQ5, Tung-Sol Reissue
Due to many requests by fans, the Tung-Sol EL84/6BQ5 has been reissued. The Tung-Sol EL84 / 6BQ5 was a popular OEM tube for American-made EL84 / 6BQ5 guitar amplifiers, such as those built by Gibson and Harmony. Due to its rugged construction and conservative ratings, it is the most reliable current production EL84 type available for use in Vox AC-30 type amplifiers. In addition, its linearity and tone characteristic make it the ideal replacement for EL84 hi-fi amplifiers, such as those built by Fisher, Scott, and Harmon-Kardon. 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.
