Like all NOS (New Old Stock) RFT preamp tubes, the NOS RFT ECC81 / 12AT7 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 RFT ECC81 tubes were made in Germany during the 1960’s.

    Wow, woke my Carvin X60 Combo amp up straight away. Great sounding tube in the Phase Inverter slot.

    Picked up another 12AT7 for a NAD Mesa Engineering SOB HOB 60/100 watt amp. Been happy so far with this tube in my Carvin X60A amplifier. The Boogie requires this type tube so I figured I would give it a try. Thank you for great service and great tubes.

    Bought this tube to calm down a Vox Lil’ Night Train. This tube in the V2 slot, with a 12AY7 in the V1, and 12BH7 in the power. WOW! Calmed down, opened up and smoothed out. Such a phenomenal difference.

    I’m always glad to buy tubes that aren’t made in substandard environments. Craig has done a great job sourcing older tubes in more than excellent condition. This tube is no exception. Bought a Brimar AT7 as well, and am anticipating a head to head. Thanks Craig!
