Knight will test anything (if it's a 600B or C), though it's "gas" test is of questionable value. Easy enough to test a tube that isn't on the chart if you have a good sample for comparison. But there is data for early and late tubes, few missing.The so-called "dynamic conductance of the EICO does not really correlate with transconductance, but SHOULD be better than simple emission test. Data should be readily available.
The Supreme may have limited test data - and does it even have a 9-pin socket?
