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.

Sovtek 12AX7 / ECC83 LPS - V1

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.
