"I’m not buying," a voice called out from behind a mountain of vinyl crates. It was Silas, the owner, a man whose beard seemed to contain the history of the seventies. "Unless you have a Thorens TD-124 in that bag, turn around."
specializes in free service manuals and schematics. A search currently returns no results for SA-370S, but it’s worth monitoring. Likewise, Manualslib.com yields only the System Fidelity SA-370 (unrelated) and other non-370S documents.
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 Solid-state power output with low total harmonic distortion
