According to technical community discussions and product listings, the SA-370S features: : Approximately 55W RMS per channel. Block Diagrams and Schematics Shorted output transistors or
If you are currently troubleshooting your receiver, I can help you interpret specific circuit behaviors. Let me know:
The relay clicks, then immediately shuts off, or never clicks at all. Manual Solution: Turn to the Protection Circuit Schematic (usually around page 15-16). Identify the DC offset sensing transistors (often Q501, Q502). The manual provides the voltage table so you can trace whether a shorted output pack or a failed differential pair is causing the fault.
The Internet Archive hosts some Technics service manuals (e.g., SA-5370), which may share similar internal design philosophies. 📋 Key Specifications (SA-370S)
