This finished board awakens a generation's simulated memory with extreme stacking. Three STK404-090 thick film ICs are selected for each channel in parallel, with six fully symmetrical stereo layouts, replicating the "pearl on the crown" of Sanyo.
This is the ultimate sublimation of classic technology. The parallel design reduces the internal resistance of the output to one-third, doubles the current output capability, and achieves a crushing level of control over the speaker, allowing for dynamic adjustment. The unique IMST insulated metal substrate technology has a heat dissipation efficiency dozens of times higher than ordinary PCBs, ensuring long-term stability under high power.
Each IC embodies the tuning wisdom of Sanyo engineers - the "golden parameters" determined through countless simulation trials are sealed in an aluminum shell to achieve a perfect balance between sound quality and stability. Pure analog continuous amplification completely eliminates the "digital flavor" of digital amplifiers, reproducing warm and mellow classic sound.
The STK series has been discontinued, and each one is an irreplaceable rare item. We adopt a fully independent power supply design, completely isolating the left and right channels, allowing this' engineer's soul 'to shine again under the ultimate parallel architecture. Limited edition production, dedicated to you who pursue ultimate simulated taste and collectible value. This is not only a power amplifier board, but also an auditory heritage of an era.
