I understand that.

So, I went and checked a NOS Tungsram EBC3 (EBC33 with a P8A socket) with a suitable socket-adapter and with the same tester-settings as for the 6Q7.
Both diodes are spot-on and the triode in the EBC shows about 10% more emission than the NOS 6Q7G.
I'd say that's fully acceptable for an emission-test and as my wife says I can't afford an AVO VCM or such I'll leave it with that
