For your consideration I have a excellent matched pair of Sylvania VT231 6SN7GTs. Identical internally these tubes have black "T" plates, bottom flat half hex getters and copper grid posts. Typical Sylvania VT231 construction! An excellent sounding tube, this pair tests very close or at typical NOS levels. Great on life tests. The base and a small portion of the tube glass on one tube has some spray paint on it, but none of this overspray has contacted the pins or any critical component. I have marked these tubes down a bit for this.
Tubes have been double tested for transconductance, gas, shorts and life on 2 world class testers. Further these tubes have been tested for gain and noise/microphonics. Gain is excellent and a great match. Both tubes are dead quiet and non-microphonic. Guaranteed to be trouble free in any application.
$ 85.00 for this pair
These tubes will be very well packed and shipped immediately upon verification/receipt of payment.
