Dario Miniwatt Made By Amperex 12AU7 Gray Plate Balanced Single NOS 12AU7A ECC82

This is a balanced single 12AU7 vacuum tube made in the legendary Heerlen factory in Holland.  It is branded Dario Miniwatt. It is short gray plates, yellow lettering, and a halo getter. These are highly sought after Miniwatt 12AU7 tubes, act quickly before they sell out!! More available upon request.

Be wary of tube vendors who claim matched tubes but do not provide test results or the equipment that they use to test their tubes.

I personally tested these tubes in my recently calibrated Hickok 600a and TV7D/U tube testers and the results are as follows:

2,300/2,425
