Tube power amp section for an Alto mini tube

[tombaker]

Hi All,
I have an old, small amp sitting around at home not being used and I want to convert it into a small tube amp.
I also have an Alto mini-tube preamp:
http://legacy.altoproaudio.com/index.php?template=3&id_prod=126939322368421&id_padre=126939121683316

which I want to use as a preamp section.

Is there a simple power amp project that anyone could recommend to run after this or would this power a 15W 8ohm speaker okay for long periods, e.g. a 4-hour rehearsal block.

I've built pedals before and mic preamps but no guitar amps. If I should post this elsewhere let me know, but I thought I'd ask around.
Thanks

Have a look over at the tiny giant, the SS amp thread, etc.

I think you want around 15w to an 8ohm speaker, if I get that right, there are a few project around here that a search will turn up that meet that spec.
