Matched Pair General Electric GE 6SJ7 6J8P Vacuum Tubes bumpus Tube One: 54/68This nearly perfectly matched pair of GE 6SJ7s was tested on our Paul Hart calibrated TV7 U for shorts, gas and transconductance. There were no shorts or gas. Transconductance measured 46 for Tube One and 48 for Tube Two where minimum (65%) is 40. They have 1 43 188 5 and 3 52 188 5 date provenance codes, respectively. I am playing them as I write in my Musical Paradise MP 301 MK3 and they sound excellent. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES.
