# 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 - 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.

Vacuum Tube - 6BY5GA, Dual Rectifier
Full-wave vacuum rectifier for television damper service
$4.90 Vacuum Tube - 6Y6GT, Beam Power Amplifier Beam power pentode primarily intended for use as an audio frequency power amplifier. It is particularly useful in applications where the available supply voltage is relatively low.$5.90
Vacuum Tube - 12AY7, Groove Tubes
This tube is closest in specification to a 12AX7 and can be exchanged with a slight drop in gain. Most companies changed over to the 12AX7 as it became more common.
This tube can be tried in later Marshall amplifiers in the first gain position, where the owner of these amps would like to drop the background noise and lower the gain level to plexi or early 70s vintage gain levels with its returned wider frequency response.
