Matched Pair Ken-Rad 6SJ7 Vacuum Tubes NOS-Testing Virginia new in box Miller 12-H6This 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.
