Matched Pair Ken-Rad 6V6 6V6GT Vacuum Tubes Black Bottles NOS-TestingThis new old stock testing matched pair of Ken Rad 6V6GT output tubes was tested on our Maxi Matcher 2 with 400 volts on the plates and a bias of 36 volts for shorts, gas and transconductance. There were no shorts or gas. Tube One drew 30. 5 milliamps' plate current and tested 2600 micromhos while Tube Two tested 31 3000. (New US made 6V6s typically test with plate current from the mid teens to mid 30s with transconductance from 2300 micromhos or so.)

It measured a perfectly-balanced 44/44 where minimum (65%) is 40/40 and 100% is 62/62
