For your consideration I have an as NOS superb matched pair of Sylvania 6SN7 GTBs. Identical internally these tubes have black offset "T" plates, copper grid posts and large halo ("O") getters. I think that this is a great sounding GTB that is very tough and typically very quiet. To my ears this tube hits an excellent balance between warmth and linearity.
These tubes have been double tested for transconductance, gas, shorts and life on 2 excellent, properly calibrated testers. Further, I have taken the extra steps of testing for noise, microphonics and gain. Gain was excellent and a great match. The tubes get my highest noise and microphonics rating of PHONO grade. Guaranteed to be quiet and non-microphonic in any application.
These tubes will be very carefully packed and shipped immediately upon receipt or verification of payment.
