Description
The 12AX7 (European ECC83) is the most widely used preamp valve in the world, found in virtually every valve guitar amplifier and countless Hi-Fi preamplifiers and phono stages. Its high amplification factor (µ ≈ 100) makes it ideal for input sensitivity and gain stages where maximum voltage amplification is required from a small signal.
This listing offers a generic new-production 12AX7 — a reliable, cost-effective option for routine preamp valve replacement where brand-specific characteristics are not a priority. An excellent starting point for trying valve replacement in a guitar amp or Hi-Fi preamp before committing to premium branded options.
Supplied as a single valve. Compatible with all 12AX7, ECC83, 7025, and CV4004 sockets.
