The Pig Noses
A 20W battery amp with a TA 7240 IC from a car radio. The distortion is made by a transistor, here a SC945. That's all about the active components. The charging technology is a joke, the speaker gets broken very easy but apart from that, the sound is fine.
The legendary amp from the movie "Crossroads". I also got it, as a collector's item. More a toy than an amp.
