Description
The STK436 is an original Sanyo thick-film hybrid integrated circuit, designed specifically for audio frequency (AF) power amplification. This 2-channel stereo module is a legendary component found in many vintage 1970s and 80s stereo receivers, amplifiers, and high-fidelity bookshelf systems.
Key Features:
- Classic Stereo Output: Provides 2-channel amplification with the warm, musical characteristics associated with vintage Sanyo hybrid modules.
- Dual-In-Line Hybrid Package: Features a robust design with a metal backplate for direct heatsink mounting.
- Low Distortion: Engineered for high-fidelity audio reproduction with minimal harmonic distortion across the standard frequency range.
- Versatile Application: Ideal for restoring vintage Hi-Fi gear, car stereos, and specialized audio equipment from the "Golden Age" of audio.
Specifications & Compatibility:
- Manufacturer: Sanyo
- Channels: 2-Channel (Stereo)
- Typical Power: 10W - 15W per channel (depending on voltage/load)
- Package Type: Sanyo Case (Typical 15-pin or variant)
- Compatibility: Replacement for STK433, STK435, and STK436 series (verify voltage requirements in service manual).
Vintage Restoration Note: When replacing an STK436, it is critical to inspect the surrounding electrolytic capacitors and emitter resistors. If the original module "blew," these components may also be damaged. Always apply fresh thermal paste for proper heat transfer.
