How should I install the new tubes in my stereo amplifier?

Hi Audiogoner,
It is time to change the tubes in my Shindo El84 amplifier, and I am ordering a new set of tubes which included the two matched pairs of Mullard EL84.
My question is: Should I install one matched set on each channel or split the matched set to half and install to each channel to keep the amp balance?
Thank you

Thanks Newbee,
Is there a reason to install that way? It seems to me if we do that way, the amp will be unbalanced. My be I dont understand clearly of how the amp works.
Thanks

Thanks Newbee.
Yes, it helps a lot. I cant find any bias pot on my amp. I will have to check with someone to see if it is auto bias.

Thanks Gentlemen,
I just talked with Matt at Pitch Perfect Audio. My amp is autobias. I only need to install a good set of tubes and i am good to go. You are right about the matched pair shoud come together.
thanks
