Sanyo STK is commonly known as Sanyo Thick Film. Under the control of the adjusted sound and high-precision semiconductor process production process, it is not a level that ordinary amateur DIY players can achieve. In addition to better sound field and resolution, the low frequency strength is much stronger
After the test, it was found that this module still has relatively large potential. The actual power is also above STK412-430, and it is powered by high and low voltage. Suffering from the lack of actual official information, we tentatively set its power to 120WX2 @ 6Ω. The working voltage is recommended to be plus or minus 45V, and the maximum working voltage should not exceed plus or minus 52V. (The schematic diagram actually needs high and low voltage power supply, there is a schematic diagram in the link for reference)
This product is a beta version, which is installed and tested before delivery. The finished plate and the radiator as shown in the picture should not be enough when actually using medium and high power. You can add a radiator according to your actual use.
The main filter capacitor of this product is second-hand disassembled ruby
