Contact Korg support in your country (e.g., Korg USA via korg.com). They will ask for your technician credentials. If you are a hobbyist, they may refuse. However, they occasionally release PDFs for "legacy products" (discontinued over 10 years) upon direct request. Be polite and prove you own an M50.
Because "Korg M50 Service Manual" is a high-volume search term, scammers target it. Avoid:
A legitimate manual is either a paid physical copy from a parts house or a clear, scanned PDF that is bookmarked.
