The Sovtek 12AX7WB has more gain and saturation than the 12AXWA version. Its warmer, darker sound is a go-to for many leading amp manufacturers, including Rivera, VHT, Demeter, and Kendrick. It can effortlessly replace the ECC83. It’s a great valve for calming down overly bright amps.
We test all the valves at real amp voltages on our suite of vintage, modern, and custom-built valve testers. Includes a test certificate showing the valve test results.
Made in Russia.
