Up for sale is a laboratory-verified JAN 5751 by General Electric. This military-grade valve features the iconic green glass print and an “O” style getter. The 5751 is highly prized as a premium substitute for the 12AX7, providing a lower gain (70 mu) for a cleaner, more detailed audio response with reduced noise.
Tested on the Amplitrex AT1000, the results below follow the Percentage Method relative to original factory specifications (Ip = 1.0 mA / Gm = 1200 µMhos).
