The Tung Sol 12AX7 preamp valve, also known by the European part number ECC83, delivers big, warm, and musical tone. High Gain with ultra-low microphonics, superb linearity, and a dynamic 3-D sound. 12AX7s are usually the first valve connected to your guitar and have a major impact on the sound. The Tung Sol 12AX7 is vibration tested and features a spiral heater to ensure low hum in AC heater circuits.
We test each valve at real amp voltages on our suite of vintage, modern, and custom-built valve testers for performance, audio quality, and microphonics. For use as a phase splitter, choose “balanced” from the dropdown menu.
