Comprehensive service and maintenance manual for the Bang & Olufsen Beocenter 1400 Type 2604 audio receiver. This detailed technical documentation covers complete disassembly and maintenance procedures for cursor drive mechanisms, including specifications for output and power transistors with corresponding impedance and winding configurations. The manual provides precise ohmic measurements for output and power transistors, detailing calibration standards using B&O RV7 voltmeter within the X1 measurement scale. Multiple schematic diagrams illustrate the MF/IF/ZF decoder section, LF/AF/NF audio amplification circuits, and the tape recorder assembly module. Includes complete technical specifications for various transistor models such as 2TR22, 2TR23, 2TR25, and 2TR33, along with capacitor designations distinguishing between polysterene, metallized plastic, plaquette, high-Q ceramic, and ceramic types. FM sensitivity measurements are documented at specific output levels and frequencies. Voltage and impedance specifications are provided for normal operating conditions and with tape recorder engaged.
