Transconductance measured 41

I have listened to it in my Bottlehead Crack headphone amplifier and it sounded great

sutured tops and a large D getter angled at 45 degrees

Matched Pair General Electric GE 6V6 6V6GT Vacuum Tubes Black Glass Amperex 5915 NOS Transconductance measured 41This 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 20. 3 milliamps with a transconductance of 2320 micromhos while Tube Two measured 21. 3 2520. (New US made 6V6s typically test with plate current from the mid teens to mid 30s with transconductance from 2300 micromhos or so.) These
