Andy,

What make and model is your tester?  Do you have a user's manual for it?  Some tester manuals define a procedure - based on known parameters for the tube - for determining the various settings for testing tubes that aren't included in the charts.

Maybe someone else has the same tester you have, and some 10Ys, and can check the results you are getting.  My tester is an EICO 667, and I have some VT 62s I could check.

RC in VT
