Transistor power amp component matching

[Miyagi_83]

Hello, everyone.
First of all, I'm sorry if this question has been asked and dealt with before. I have done some searching, but haven't been able to figure out a straightforward answer. I'm new to solid state amplification. Now, to the point.
I've been looking at Rod Elliott's 40W power amp design and I don't know which components should be matched. I started reading teemuk's book, but for now it's quite a bit to digest, so I'm taking my time.
So, should I look for matched pairs of any devices found here?

Thanks for any input.

Matched components are not really needed and are a waste of money unless you get them from a trusted source.

If you are using ESP's circuit boards, make sure you don't mix up the two R24s and Q12s. The amp won't work and you will likely damage several components.

Thanks a lot for the reply, Loudthud.
