What about one of those little chip amps that only make about 10 watts or so? They are cheap as chips if you pardon the pun, so not much lost if it doesn't work out.
Shame you are not close to me - I have an Audion Silver Night 300b stereo, which outputs 7W per channel. It's not doing anything at the mo, so you'd be welcome to borrow it and see how that sort of thing fares.

Forget the past, it's gone. And don't worry about the future, it doesn't exist. There is only NOW.
