JJ ELECTRONICS 12AX7/ECC83S GOLD PINS

These are the gold pin version of the standard ECC83. These tubes are immediately discernible 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. An excellent tube in all Marshall amps in the three preamp positions.

Factory selected tubes with gold pins. These tubes provide high gain without the usual noise and microphonic problems you would expect. This is great sound and value for your money.

ECC83S is 12AX7 high gain preamplifying double triode. Thanks to its design it also peforms with very low noise and microphonics. Harmonically rich, with a detailed low end and a warm high end.
