Matched Pair General Electric GE 6V6 6V6GT Vacuum Tubes Black Glass PCL805 Nonal Tube Four: 34/2240 where new/nominalThis new old stock testing matched pir of GE 6V6GT output tubes was tested on our Maxi Matcher 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 24. 1 milliamps with a transconductance of 2640 micromhos while Tube Two measured 24. 8 2760. (New US made 6V6s typically test with plate current from the mid teens to mid 30s with transconductance from 2300 micromhos or so.) These
