The TAD 12AT7 with matched sections solved a big problem in my Dual Showman. The Phase Inverter now delivers exactly the same drive voltage to both sets of power tube grids in the correct manor, without any circuit adjustments whatsoever. This is the perfect tube to allow a completely stock 50-year-old amplifier to work like the day it was new!

Used in Vox Ac15C1X for the verb driver. I like the TAD tubes!

I put two of these in my SuperSonic. It was eating reverb drivers at an alarming rate and I did not want to lose another NOS so I tried these. Held up for the first two hour gig and the reverb sounded the best I have ever heard it sound.
