Matched Pair Ken-Rad 6SJ7 Vacuum Tubes NOS-Testing Virginia Please rely on the picturesThis new old stock testing, nicely matched pair of Ken Rad 6SJ7s was tested on our Paul Hart calibrated TV7 for shorts, gas and transconductance. There were no shorts or gas. Transconductance measured 58 for Tube One and 60 for Tube Two where minimum (65%) is 40. They have G 5R and G SR date codes, respectively. I am playing them as I write in my Musical Paradise MP 301 MK3 and they sound excellent. They are microphonic and are fine in the preamp
