Description
Bring clear analog sound back to your legacy bookshelf systems with the STK402-030. Developed by Sanyo using their unique 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 up to 30W per channel into 6Ω speaker setups.
Key Features:
- Dual-Channel Class-AB Output: Delivers a balanced stereo power stage (30W + 30W max) with low crossover distortion for clean, warm analog music staging.
- Miniaturized Footprint: Built on a modern, low thermal resistance substrate that slashes the overall physical footprint by roughly 60% compared to legacy Sanyo series blocks.
- Pin-Compatible Versatility: Belongs to a uniform, standardized series ranging from 20W to 120W per channel, sharing the exact same footprint layout across the series framework.
- Integrated System Support: Fully pin-configured to tie smoothly into standard external standby microcontrollers, speaker muting grids, and load-shorting protection loops to halt power-on transient shock "pops."
Technical Specifications:
- Manufacturer: Sanyo (Original New Old Stock / High-Quality Replacement)

- Recommended Operating Voltage: ±22V (Maximum Supply Voltage: ±34V)
- Output Load Impedance: Optimized for 6Ω speaker systems
- Primary Applications: Main audio power stage in mini-stereo shelf towers, compact bookshelf sound blocks, and active multimedia desktop monitors.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Proper thermal grounding is vital to protect this compact module from internal damage. Scrape away all legacy dried thermal paste from your chassis mounting bracket. Apply a fresh, thin, uniform layer of high-grade silicone thermal compound across the metal backing plate of the STK402-030 prior to fastening it securely to the heatsink.
