(New 807s typically test from the mid teens to mid 30s with transconductance from 2200 micromhos)

5 volts with adapters (not included) and they sound tremendous even though they are running with a lowered filament voltage

Transconductance measured 3100 micromhos with a plate current draw of 37

generous flashing and an anode radiator for cooler operation and longer life

It measured 38/34 where minimum (65%) is 40/40 and 100% is 62/62

Matched Pair General Electric GE 6SJ7 6J8P Vacuum Tubes Valves NOS-Testing CD Compact Disk (New 807s typically test fromThis new old stock testing, 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 64 for Tube One and 68 for Tube Two tubes where minimum (65%) is 40. They have NU 188 5 and 3 09 188 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
