Miniatur-Potentiometer 25k horizontal PT10

Retainer for 6550 / KT88 Tubes

6 tubes, matched as sextet

Very credible 6550 so far.
We recommend this 6550 for bass amps which are working with 6550 tubes, especially Ampegs.

Meets the 12AX7 / ECC83 specification but has a imporved grid construction. Files:

Sonically similar to the "normal" JJ 12AX7, but the overall sound is "fuller" and "stronger" with a more powerful bass. Visually, compared to the normal JJ 12AX7, the long anode plates stand out, as well as a slightly higher current. Suits well in guitar and bass amps, but also in audio and high-end areas.

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.

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.

Electro-Harmonix has released a low noise, low microphonic version of the 12AX7 that meets all specifications required for the tube to be designated 7025. The original 7025 tube was a 12AX7 that was tested and selected for the lowest noise and microphonics for use in the critical first preamp stages of amplifiers where noise and microphonics could be an issue. In order to ensure that the 7025 specification is consistently met, Electro-Harmonix has redesigned the structure of the 12AX7 and has implemented construction techniques to ensure the absolute lowest noise and microphonics possible. In all samples tested, noise and microphonics could not be detected.

The Electro-Harmonix 7025EH has a mid-range that gives clarity and definition to the sound and a smooth top end for warmth and balance. With these characteristics, along with the exceptionally low noise and low microphonics, the Electro-Harmonix 7025EH will work equally well in vintage and modern high-gain guitar amplifiers, as well as sensitive phono preamps.

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

Sweet and warm sounding preamp tube with high gain. We recommend this tube for guitar/bass amps.
