JJ 12AX7 ECC83S .
These tubes are immediately discernable from other 12AX7. They have a construction that is similar to a frame-grid tube - similar to the Telefunken ECC803s. This construction makes them very rugged and reliable. This is one of the best new 12AX7 for any guitar amp. It is very musical - rich with great harmonics. JJ12AX7 ECC83S
