Like all NOS (New Old Stock) RFT preamp tubes, the NOS RFT 12AT7 / ECC81 is a low noise and low microphonic preamp tube. It sounds great and is especially good for guitar amps because of its rugged construction. These were branded Zearix for retail marketing in England. They were made in Germany during the 1960’s.
