Matched Pair General Electric GE 6SJ7 6J8P Vacuum Tubes 59 Fiftynine forward sound with great bassThis 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 50 for Tube One and 54 for Tube Two where minimum (65%) is 40. They have 2 30 188 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.
