This is a single Amperex Bugle Boy 12AX7 tube. It was manufactured in the legendary Heerlen factory (code mC5) by Amperex and has a semi-faded bugle boy picture. This tube is perfectly balanced. This tube was manufactured to rigorous specifications for reduced noise and microphonics. It has long gray plates, white lettering, and D-foil getter. These are highly sought after Amperex 12AX7 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:
