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.

These power amps really upgraded the tone of a cheap Monoprice 15 watt amp that I purchased. It sounds as good as any Boutique camp now

Holds up well in amps that can be hard on tubes. My favorite EL84 for amps that run a little on the hot side.

Installed in Bugera V22 - great punch and power - lots of headroom - be sure to bias your amp after installing.

I installed a matched quartet of these along with a set of Tung Sol 12ax7s in a customer's Vox ac30. They sound absolutely wonderful

These tubes REALLY make a difference. My tech kept changing things in my amp and the only thing that REALLY brought it to life are these power tubes.

Used in Fender NOS Tweed Blues Junior w/TO-20 output xfmr, Eminence 12" speaker. Guitar: '84 Fender "Pawnshop" Tele w/ ThinLine '69 pickups. Tung-Sol tubes replaced JJ EL84s.

The Tung-Sol tubes have a larger bottle than the JJ's. There's plenty of clean headroom with a very noticeable improvement in tone and freq. response. Lows are deeper and tighter. Highs have that glassy Fender "ring in a bell" harmonic complexity. Individual string tone, definition, and touch sensitivity had more detail than the JJ's. The amp sounds well-balanced with a broader range of tones.

The Tung-Sol EL84 puts the Tweed Blues Junior in the same sonic space as the 5E3 Tweed Deluxe. I'm very pleased with the total performance.
