☆☆☆☆☆☆☆☆ (8/10)

The Technics SE-CH404 is most desirable as part of a complete SC-CH404 system. Fully functional amplifiers in excellent cosmetic condition are increasingly difficult to find because many original systems have been separated over the years, making complete matching sets more attractive to collectors.
Description
