He disassembled the parts of the amplifier in order from the outside to the inside: first removing the covers on both sides, then the sliding rods and brush blocks, followed by the drive rods and bevel gears, and finally taking out the dual-axis motor and circuit components.
Each piece was carefully placed on the floor by him, sorted meticulously: plastic components on the left, metal parts in the middle, and circuit elements on the right.
Even tiny springs and screws were piled separately, not mixed together.
When it came to the circuit elements, Chen Lizhou encountered a problem—several thin wires were tangled together, and he couldn't figure out their corresponding interfaces.
Rather than forcibly pulling them apart, Chen Lizhou reopened his computer browser to search for the circuit diagram and disassembly manual of the amplifier.
The information on the web was scarce, and he had to flip through several pages before finding a teardown video shared by an enthusiast.
