GENERAL INFORMATION The KRELL KBL (Krell Balanced Line) and KPA (Krell Phono Amplifier) present many new concepts in preamplifier design. The traditional preamplifier contains both a phono section and a line section. The KBL and KPA divide these functions into two separate units. This was done for several reasons. The primary motivation was to allow adequate space to accommodate the latest evolutions of preamplifier circuitry and functions. 2
