Matched Pair JJ 6V6 6V6S Vacuum Tubes Apex-Matched NOS-Testing 1st Quarter MSR 46 and 50 where minimum

46 and 50 where minimum (65%) is 30 and 100% is 47

9 milliamps where new 6L6GCs typically test with plate current from the low 20s to mid 30s and transconductance from 2200 micromhos or so

Transconductance readings are 30

They have top D getters

and they measured as follows:

Matched Pair JJ 6V6 6V6S Vacuum Tubes Apex-Matched NOS-Testing 1st Quarter MSR 46 and 50 where minimumThis new old stock testing, nearly perfectly matched pair of JJ 6V6S 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. They were also Apex Matched with readings very similar to our own. Tube One drew 24. 6 milliamps with a transconductance of 3060 micromhos while Tube Two measured 24. 7 3060. (New US made 6V6s typically test with plate current
