This may be encouraging: When I tested some older used US Tung-Sol 6550s they were around 88-90% on my Eico 667, a bit disappointing. But when I got the Hickok tester the same tubes tested very high, and with trustworthy readings. I did use KT88 test data (all Hickok supplies). I suspect the 667 is a bit off for 6550s.
