Default Small tube amp based on 6N6P

Hello!

I'm thinking of building a small mono-speaker with integrated amp.

The speaker element I will use is a 4", and has a sensibility of 94dB.

Does anyone have a very simple and good schematics or idea for how to build the amp?
I haven't decided if I should go with PP or SE, would you think SE could be power enough?

Maybe this schematic is something to use? The SE looks quite easy, though I don't understand the "Parallel"-thing:

Please comment!

Could this be a good transformer to use?

What do you think of these speakers?

Here are some info on the 6N6P

I've looked at the specifications for the 6N6P.
It's an interesting tube and may sound good as the output stage in a SE configuration.
Both sections in parallel.
You'll need another stage or two to drive the 6N6P.
What are your thoughts on the input/driver stage(s).

I've built a couple of SE amplifiers using 6BM8 triode/pentodes and with 6DN7 dissimilar triodes.
I have no experience with the 6N6P tube.

I'd like to know the outcome of your project.

Thanks for your very quick reply!
Since this is my first DIY-tube-experience, I'm not sure what I need. I thought the 6N6P tube it self was enough for a so small speaker, I'm thinking 4-6 watt. I might need to study the SE theory first...

I hope you have patience

Can I use this input stage?

Would seem a little strange though?
