Pair of Electro-Harmonix 12AX7 EH Preamp Vacuum Tube

good packaging ---used in my high quality tube amp for music--sound even better than last tubes -thats all-they took a couple of hours to break-in running with volume up--then the sound got richer and richer

Was as described

As advertised. Subtle increase in my clean headroom.

well made low price fast delivery, works for me :)

My tubes broken and I was looking for this without paying a high price for them.I would recommend this to anyone.
