What Tung-sol say about their valve - Due to many requests by fans of our Tung-Sol line of tubes, 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.
Note: These tubes have a slightly larger diameter than other EL84 tubes so they can not be installed into some Marshall DSL201 or DSL401 amplifiers, some reissue Vox AC15 amps, and Bad Cat amps.
