JJ 12AX7 / ECC83S

4 tubes, matched as quad

In 1959 Tung-Sol developed a premium, up-rated version of the 6BQ5/EL84 for use in industrial and military circuits. This tube was designated 7189. Due to its higher plate voltage rating and increased clean headroom, it became a favorite power tube for use in medium power stereo amplifiers and receivers made by H. H. Scott, Sherwood, Fisher, Lafayette, and many other hi-fi manufacturers. It was also used in high-end guitar amplifiers manufactured by Magnatone. Due to its increased ratings, it was considered as an upgrade for 6BQ5/EL84 amplifiers for increased performance and reliability.

The original 7189 tube production ceased in the early 1980s and vintage 7189 tubes have become expensive and hard to find. In order to allow these fine vintage 7189 amplifiers and receivers to continue be used, the Tung-Sol 7189 tube has been reissued. The 7189 Tung-Sol® reissue is built to the same specifications as the original 7189 Tung-Sol for the high fidelity and performance expected from the vintage 7189 amplifiers and receivers produced in the 1960s and 1970s.

Strongly committed to quality manufacturing, Tung-Sol tubes have always been known for their reliability and great tone. Today's new production Tung-Sol tubes are constructed with the same commitment to quality and reliability. Tung-Sol tubes reflect the best in vintage Tung-Sol construction with unsurpassed tone and reliability.

Tube-Town E83CC Preamp-Tube

High-quality 12AX7 / ECC83 / 7025 preamp tube with low background noise and reduced feedback tendency due to short anode plates, as well as a powerful bass and a dense sound. Very suitable for input stages with high amplification or amplifiers with generally high gain.
Dropin replacement for all 12AX7, ECC83, 7025, and E83CC tubes.

Application Notes

• Heater operation: The tube can be operated with 6.3V or 12.6V, depending on the circuit design.
• Grid resistors: It is recommended to use grid resistors of at least 1MΩ to ensure stable functionality.
• Coupling capacitors: Capacitors with low capacitance (typically 0.1µF) are recommended to minimize high-frequency interference.

JJ EL84 #05 - Soft Plus

• Not so hot than the #06 selection but still nice punch
• Recommended for Fender Blues Junior and Pro Junior and similar amps.
• Price for one tube.

FAQ: If I order two or more of these tubes, are they all "the same"?
Yes, the tubes are all "matched" and selected for the in the description mentioned amplifier.
FAQ: Can I replace the tubes myself or are adjustments needed?
Adjustments are not possible on the listed amplifier (unless a bias potentiometer has been added afterwards). The replacement can therefore be done without adjustments.

SoZo BlueMolded Vintage Capacitors™

The BlueMolded line of capacitors are retrofits for Astron or Blue Molded caps used in vintage tweed, brown, and blackface Fenders™. These capacitors amazingly capture vintage Fender tones of the Blackface era, and the famous 1959 tweed 5F6-A Bassman era.

4 Tubes matched as quad
Superior high-voltage Power Pentode with traditional brown base. Faithful re-issue of the original Russian EL34. Preferred by many guitarist for its brighter sound with more mid-punch. Also in demand by Hifi enthusiasts.
