The emissions test results vary with the cutoff setting.

That's how it works with the B&K testers, you can make a weak tube check good by cranking up the cutoff voltage.
I have no experience with the CR70 so I can't say on that.

I have a tube I rejuvenated that has great emissions but the cutoff won't respond all, still it makes a bright raster.
