Question about JJ 6L6GC tubes

[poke01]

I recently bought a set of JJ 6L6GC tubes to be installed into my Mesa Boogie Dual Rectifier. When the tubes were installed by a tech, he mentioned that the tubes were not an actual quad set. It seemed they were two matched pairs sold as a quad set. I spoke to the salesmen who sold me the tubes and he said they were within 2% of eachother and they would be fine.
I'm new to the tube world. What are your thoughts? Will these tubes be ok installed and biased in my amp or should I send them back?

Thanks!

You'll be fine...just put one matched set in the outer 2 sockets and the other set in the middle 2 sockets. No worries, just did the same in my DR.
