Matched Pair General Electric GE 6V6 6V6GT Vacuum Tubes Black Glass PCL805 Nonal Transconductance measured 1320 micromhos andThis 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
