Which EL84s for Lectron JH30 integrated amp?

I recently purchased this French-made hybrid integrated and I'm trying to figure out which EL84s will work best in it (it takes 8). It's a unit that is not often seen in the U. S. and I find that there's scant info about it. Since I don't speak French I'm hesitant to write to Lectron and ask them, but if anyone knows which EL84s come with it when new that would be a good jumping off place. Or, if you have one and have settled the tube issue for yourself please let me know your findings.

With thanks,
Lee
