Sanyo STK Amplifier Schematics
Sanyo production STK series power amplifiers integrated belonging to the original circuit diagrams diagram of the manufacturer (SANYO) is the problem will not be a market original NGO integrated hard to find even copy the original design made in accordance with the general power transistors low quality but fake though a lot amp integrated from the transistor from Anfi etc.. gives a much better sound.
