I think this qualifies ...

I think this qualifies, it's class A and delivers 4w RMS into 12 ohm from a 14v DC supply.
Is this an original design ?? I like to think so, but others should decide !!

PS I will be impressed if someone can figure out the topology from this low res photo !
(clue - it's unity gain)
