Any Tube advice?

[Loserchief]

so i just ordered myself an Ibanez Valbee 5W Class A all tube combo. Thought it already sounded great when playing it stock in the shop(would have bought it there but ebay just is cheaper), but i think that with a replacement for the cheapo chinese tubes that are stock in it, it should sound even better.
I also ordered one JJ ECC803s/12AX7 and an Electro Harmonix 12AX7EH for the preamp so that i can test both and see what i like better.
Real question now is the power tube. It runs with a single 6L6 tube in the power section(odd i think for an amp of this size,even the 50w engl combos use smaller tubes) Any advice on which model to use and where to buy it cheapest(europe)?
To clarify, this amp is already pretty high-gain and i want to keep that characteristic, so i'm not into vintage tubes.

im assuming that the amp is single ended class a? ive never seen one.

i think a kt66 would be great in there. the gtkt66hp is the best new one available. big bottom and a huge tone.
how tight is the area the tube is in? the kt66 is a BIG bottle

jep,it's class single ended class a. Spacewise i habe no idea right now since i don't have it yet. But is a kt66 really a direct replacement for a 6l6 or would i have to rebias or anything like it? I'm pretty new to the subject of changing tubes and such since my powerball has JJs stock and is quite fresh,so i never had to deal with it upto now.
