Egnater Rebel-30

What is the idea behind of these PC/TC data for Ruby Tubes?

It will just the the Plate Current and TransConductance they measured with their test rig at at particular plate voltage and bias current. It tells you how well they are matched at that plate current and bias voltage. Hopefully they will still be matched well enough if you chose to run them at 20mA like the Egnater.

One more thing. I almost hate to say this as I don't want to start another storm about modern tube manufacturing. I've not had good luck with TAD's of late. If you have a tube tester, test them BEFORE you install them.

I use TAD some years ago and I've never had any problems with TAD never!!....I installed that in my EGNATER rebel 30 and sound very powerful and very very clear!!....you bad experience with TAD was a causality I think nothing is perfect man; sorry for you my friend.

Opacheco.
