Sylvania 5932 6L6WGA Output Tube Valve Industrial Version

Sylvania 5932 6L6WGA Output Tube Valve Industrial VersionThis industrial grade Sylvania 5932 6L6WGA output tube was tested on our Maxi Matcher 2 for shorts, gas and transconductance with 400 volts on the plates and a bias of 48 volts. There were no shorts or gas. Its plate current draw was 25. 3 milliamps while it measured 2380 micromhos where new US made 6L6s typically test with plate current from the low 20s to mid 30s and with transconductance from 2200 micromhos or so. I am playing it in my Stereo 70

This cooling chimney/shield fits a 6L6GC nicely and with room to spare on top
