Sa-370s Service Manual - Technics

The schematics provide a complete structural map of the receiver's electrical pathways. They trace the audio signal from input jacks (Phono, Aux, Tape Monitor), through the preamplifier and tone control stages, to the driver and power output blocks. Volts-per-node data points are explicitly labeled to allow rapid diagnostic probing. Circuit Board Layouts and Foil Patterns
