Sylvania 5814A, NOS, Boxed
Military version of the 12AU7 / ECC82, designed for increased reliability and performance, with lower microphony and noise levels.

• NOS
• Made in USA
• High Grade 12AU7 / ECC82

TT Selection: V1 - Low Noise
This tube is selected for sensitive input stages (V1)

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.

4 tubes, matched as quad

The Sovtek 5881 delivers a warm, round tone that "sweetens" any vintage or modern guitar amp design. Chances are if an amp uses 6L6-style output tubes, it has Sovtek 5881's in its sockets. Built to rigid military standards, the 5881 will tolerate higher voltages than any other 6L6. In fact, they're frequently used as replacements for the old 7027 model in vintage Ampegs.

Damping material made of polyester wool with excellent damping properties. Can be handled and fitted easily.
Packing unit: 125 g (2 mats, enough for a volume of up to 20 l).
Dimension per mat: 63 x 33 x 3,5 cm

TT Selection: V1 - Low Noise
This tube is selected for sensitive input stages (V1)

This tube is recommend to tame the gain of an amp and make it sound "sweeter". The 5751 has only a gain of 70 instead of 100 like the typical 12AX7/ECC83 tube type and can be used as a drop in replacement for 12AX7 / ECC83 tubes.
