The tubes. Red to be matched for gain a d interelectrode capacitances. Matching is usually done in a test jig with low RF drive. Matched pairs are. It nearly as important as most people think depending on the amp design. What kind of amp are they for?
 
Its for an Acom 1011 (y)

You have to have faith in the person who sold them to you (don't use that BIG outfit out of California, they don't "Match" anything.

You unit has a biad adjustment that will compensate for the difference in currents drawn by the individual tubes.

I just had a good look at the typos in my post. I guess I need more practice texting from my new phone especially from work at 4:30 in the morning. :D

I gave up on trying to text correctly, thumbs to big for those small pads, so whoever I text to either needs to interpret the mistakes or ask me what the heck I was trying to say.
