Maintained in May 2020. John Carle's slim design “flat preamp” is the first control amplifier equipped with an original module developed in-house. The straight, core tone with thorough simplification and carefully selected high quality parts is the model that later became the basis for Mark Levinson preamps. The exterior has small scratches and dullness (Tetsuji Oikawa)
