So only a week after I repaired my Sony VCR's power supply without the benefit of the service manual, guess what I came across on an unrelated search? No idea why I couldn't find this before; all I could see was shady sites that claimed to have it behind their paywalls. So in case anybody needs this in future, here's a copy of the PDF (13MB).
This service manual covers:
- Sony SLV-373 (AEP model)
- Sony SLV-373UB (UK model)
- Sony SLV-373VP (West German model)
