See this paper, it nicely discusses these, you get a good glimpse on what are involved when designing such amplifiers:

Hi Gyula,
I've had a chance to look at the links you posted properly, and i realise that your first link did answer my question about as well as anything could. Thanks. :)

The design with the two BLF177s is exactly the sort of thing i was looking for, and the build cost would be under £100 too. Plus there's loads of good info in there explaining the theory. It looked too technical yesterday - i was in a building mood - but today it makes sense...

I will study this, and the other papers, and see if I can learn it...

Thanks again.
Regards, Tim

Hi Qwert,
those are cool devices - but i think they can only amplify an AC supply... Would be good for modulating an existing signal, but not for generating one...(?)

My feelings were also this kind at first. But as I keep it reading deeper and deeper, I see something different. But only experimenting can prove or disprove this for sure.
