She uses a Hickok 6000A. I have bought from her before and had no problems. However, I have only bought tubes from her for guitar amps because I know she can't do proper matching for audio, although I bought a handful of 7247 to do my own matching with.
With a plus or minus 15% range of accuracy on a 6000A, that is a possible 30% the readings could be off for gm.
