Brand New Matched Octet (8) JJ ECC803S / Long Plate 12AX7 Vacuum Tubes

The JJ ECC803S / 12AX7 Long Plate is a high gain tube. The long plates make for higher gain and a warmer fuller tone but they also increase the chance of microphonics so these are best used in guitar amplifiers or other high gain applications. Almost every sought after vintage tube has long plates so the tonal differences are worth the risk. These are comparable to the Telefunken ECC803S which is the tube that JJ had in mind when they designed it.
