Matched Pair Ken-Rad 6V6 6V6GT 6P6 6P6P Vacuum Tubes Black Glass Stereo Vinyl H-71142 The diodes measured 78 andThis matched pair of Ken Rad black glass 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 measured 17. 9 milliamps' plate current, 2590 micromhos and 18 2480 for Tube Two. (New US made 6V6s typically test with plate current from the mid teens to mid 30s with transconductance from 2300 micromhos or so.) These tubes have
