This is a pair of GE 5 Star 5751 tubes. The 5751 is interchangeable with the 12AX7 but it has a slightly lower amplification factor.  These tubes were manufactured to military specifications for reduced noise and microphonics. These tubes have short gray plates, double micas, red lettering, and halo getters. These are highly sought after GE 5751 tubes, act quickly before they sell out!! More available upon request.

Be careful buying tubes from other sellers who list "matched pairs" but do not provide test results or specify the equipment that they use to test their tubes.

I personally tested this tube on my recently calibrated Hickok 600a and TV7D/U tube testers.

The results are as follows:


1,850/1,800

1,850/1,775
