JJ EL34 Version II - QUAD

4 tubes, matched as quad

Premium power beam tetrode continuing in the Tung-Sol legacy. The ultimate in musical tone and smooth overdrive, STR delivers the sound that established Tung-Sol as the benchmark of quality.

2 tubes, matched as pair

Rugged and wonderful-sounding Power Beam tetrode that performs flawlessly at up to 475 volts. Great replacement for single-ended amps such as Fender Champ, or high plate voltage amps like the Fender Deluxe Reverb.

• Specially developed cathode coating
• Tri-alloy plate material
• Carefully aligned grid

JJ EL84 #06 -Standard

• Recommended for Peavey Classic 30 / 50, AC30 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 amplifiers.
  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.

EH 12AX7 / ECC83

• The 12AX7EH provides high gain with ultra low noise and detailed, musical tone that rivals the most desirable NOS types.

Very linear working 12AX7 / ECC83 with long anode plates and spiral heating, which makes the tube less sensitive to interference from AC heating.
We recommend this tube for audio and high-end amps as well as for "modern" Fender amps with more overdrive, but also as an input tube in old Marshall JCM800s.


Note: Tubes equipped with long plates are commonly associated with a "warmer" or "richer" sound, whereas those with shorter plates tend to deliver a "tighter sound". However, tubes featuring long plates exhibit increased sensitivity to vibrations and mechanical disturbances, rendering them less ideal for critical applications.

Tube-Town 12AX7 / ECC83 Preamp-Tube

The TT12AX7 impresses with its fine and detailed reproduction of the highs, which is maintained even at high amplification levels. Due to a higher H3 part, the TT12AX7 sounds significantly cleaner than many other 12AX7/ECC83 tubes, which makes the bass range appear much tighter. We therefore especially recommend this tube for styles such as clean, crunch, and metal, where high amplification and clear transparency are required.
