This new old stock-TESTING matched pair of GE 6SN7GTB dual triodes was tested on our Paul Hart-calibrated TV7/U for shorts, gas and transconductance. There were no shorts or gas.

Transconductance measured 82/79 for Tube One and 80/81 for Tube Two where minimum (65%) is 50/50 and 100% is 77/77.

They have side, harp getters; copper support rods; great flashing and 56-26 188-4 and 58-13 188-5 date/factory codes, respectively.

I have played them in my Radio Craftsmen RC-2 monoblocks and they sound great. They are dead quiet when the volume is muted and have excellent frequency response, sound-staging, and dynamics.
