Description
Restore crisp, high-fidelity power to your compact audio gear with the STK402-090. 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 stage, delivering a robust 50W to 80W per channel into 6Ω speaker loads.
Key Features:
- High Power Stereo Output: Delivers clean and stable dual-channel amplification, making it the perfect drop-in replacement for worn-out mini-component stages.
- Class-AB Efficiency: Blends low crossover distortion with optimal thermal management, retaining that classic, dynamic analog sound profile.
- Miniaturized Form Factor: Features Sanyo’s advanced low thermal resistance substrate, shrinking the overall footprint by about 60% compared to vintage generations to fit tight modern-classic PCB layouts.
- Protection & Muting Support: Pin-configured to connect flawlessly with external standby controls, muting circuits, and load-shorting protection arrays to eliminate power-on "pop" transients.
Technical Specifications:
- Manufacturer: Sanyo / Panasonic
- Package Type: Compact SIP-14 / SIP-15 Variant (Single In-line Package, 14-Pin Active Layout)
- Output Load Impedance: Optimized for 6Ω configurations
- Primary Applications: Replacement power output block for bookshelf stereo receivers, mini-component sound towers, and multi-channel home theater amplifiers.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Due to the high power density of this compact module, exceptional thermal bonding is mandatory. Completely scrape away all legacy, dried thermal compound from your amplifier's main heatsink bracket. Apply a fresh, thin, uniform layer of high-quality silicone thermal grease across the entire metal backing plate of the STK402-090 before fastening it down firmly.
