Description
Restore ultimate high-power output and rich, warm musical staging to your audio system with the STK403-130Y. Engineered by Sanyo using their proprietary Insulated Metal Substrate Technology (IMST), this genuine-spec thick-film hybrid integrated circuit acts as a dual-channel (stereo) Class-AB audio frequency power amplifier, delivering a stable 100W continuous RMS per channel directly into 6Ω speaker configurations.
Key Features:
- High-Power 100W Stereo Block: Supplies a sustained 100W + 100W RMS (and pushes up to 150W dynamic peak per channel), giving larger bookshelf speakers and floor-standing cabinets incredible headroom and punching dynamics.
- Acoustic Fidelity & Low Distortion: Maintains clean, authentic sound staging with a total harmonic distortion (THD) rated under 0.4% across the entire 20Hz to 20kHz frequency range.
- Unified Series Trace-Compatibility: Shares layout blueprints with alternative power tiers in Sanyo’s pin-compatible family, making it highly preferred by technicians for direct, stress-free drop-in circuit board replacements.
- Built-In Standby Circuit Path: Features pin-mapped support to pair cleanly with motherboard system microcontrollers to support energy-saving low-power standby operations.
- Anti-Pop Shock Noise Abatement: Internal trace structure naturally suppresses power supply switching transients and sudden speaker "pop" sounds during power-on and power-off routines.
Technical Specifications:

- Primary Applications: Main audio frequency power stage in high-output home theater receivers, mini-component stereo shelf systems, active multi-media setups, and custom DIY setups.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Because a 100W+ per channel dual stage concentrates immense thermal energy into a single block, proper thermal grounding is non-negotiable. Completely clean away all old, crusty thermal paste from your chassis mounting bracket. Apply a fresh, thin, uniform layer of high-grade silicone thermal compound across the entire metal backing plate of the STK403-130Y prior to fastening it securely to the heatsink.
