[hot]: Technics Sa-370s Service Manual

Here is how to apply the Service Manual to common issues with the SA-370S:

Left channel works; right channel sounds like a blown speaker (but it isn’t). Manual Solution: Check the PCB layout for the tone control board. Locate the notorious “orange drop” capacitors or the function switch relay. The parts list identifies which capacitors are in the signal path (e.g., C201, C202) so you can recap them with low-leakage Nichicon or Panasonic replacements. Technics Sa-370s Service Manual
