Note: Logos may vary from tube pictured, some are branded Ei, RCA, GE, National, etc.
Limited stock of Ei ECC83/12AX7 preamp tubes available. Online reviews and comments you'll find will tell you that these vacuum tubes sound incredible, but are prone to microphonics. We do NOT recommend for guitar amplifiers unless used for phase inverter. However in a hifi preamplifier or rack mount gear where vibration is a non-issue, these tubes will work well and sound beautiful.
