Potentiometer for Marshall JCM800, 100 kOhm linear

• Size: M9 x 0,75
• Price per nut

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.

• 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.
