This IC is part of a series where different power ratings often share the same pinout, allowing for easier PCB upgrades.
For hobbyists and repair technicians, the STK412-230 is both a relic of high-end analog audio and a challenge to maintain. Since Sanyo stopped production, many modules found today are "new old stock" (NOS) or salvaged from legacy hardware. Are salvaged Sony ICs worth keeping? - Facebook Stk412-230 Datasheet Pdf
Optimized for high-voltage operation, often requiring a split power supply (e.g., to ). This IC is part of a series where
