Description

New Plate Current Matched Quad of Tung-Sol EL84 (6BQ5) Vacuum Tubes

Due to popular demand, 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.

Will work in place of: EL84, 6BQ5, 6BQ5A, 6BQ5W, E84L, 7189, 6P14P, 6P14P-K, 6P14P-EV

Testing and/or Matching

At VIVA TUBES, all of our customers get the same high standard of testing and matching. Some sellers charge more for premium matches but we believe all of our customers should get the same level of quality and service. 

Tubes are tested and/or matched at full operating voltage with regulated power supply on a Maxi Matcher tester for general mutual transconductance (Gm). In addition, power tubes are tested/matched by plate current (Ip) and preamp tubes are tested/matched by gain. Rectifier tubes will be tested for emissions on a calibrated military grade tube tester. 

Our goal is to match within 5% with an upper limit of 15% (15% is the industry limit to consider a set).

Hand written test data included.

Note that we do offer a few models which are tested & matched at the factory. They will be matched by the same parameters (Ip & Gm) but to the manufacturer's standards. Factory testing will be indicated in the item title and description. 

Guarantee

We offer a minimum 90 day guarantee covering functional defects - including noise unless otherwise stated. The guarantee period begins the day you receive your order.

    Great tubes for my Class A 30-watter

    Posted by Scott Freeman on 4th Feb 2020

    I've tried basically every readily available EL84 in my Orange AD30, and these tubes came in first. They break in fast, last long, and have the best tone (I realize this is very subjective). Let's just say that they most faithfully compliment/add to how my amp is meant to sound.
