Late 50's early 60's long plate version. Lightly used, tests as new.
Those ANOS GE-12AX7 long-plates you recently sent me sound noticeably warmer and smoother than the previous ANOS GE-12AX7 long-plates I purchased somewhere else online. What a rich, complex, beautiful sounding tube in overdrive, but also in clean modes! They sounded so good, I used both of them – one in V1 and one in V2. This is probably the best 12AX7 I’ve heard (for my tastes anyways). Cool! (Dumble style amp)
