RE: Anyone buy tubes from NOS Tube Store in Turkey?

The tubes I bought, 12AT7WAs were perfect when I measured them. I don't remember seeing anything about them being measured for microphonics.

I've used a George kay tube checker that allowed me to listen to each triode for noise and I could tap on it to hear what happened. It didn't allow me to measure microphonics.
