great reciever. amazing sound and looks. my family has owned one since new, they actually put out around 80 watts at 4 ohms, they are very underrated. the build quality is insane and the wood is real wood not plastic. the sound is very warm and rich. i cannot put my finger on it. it has a far richer warmer sound than modern amplifiers. made in the golden age of audio. i do not dislike this amp in any way whatsoever. these cost 400 Australian dollars in 1979. they dont make them like they used to for sure
