What do we have here?
In the power section we see some filtering, notably the LC filter. Nice idea. The gold rectangle is the power switch, the diode is probably for reverse polarity protection. The other stuff, including Q1, unknown

To the left of the chip we see the decoupling caps, the input caps (electrolytic) and input RF filter. The other electrolytic may be on the 5 volt supply.

The TA2024 chip is on a ground plane. No cooling tho. The 50K volume pot is in front of it. No idea of its quality. It looks nice.

To the right of the chip we see snubber diodes and the power decoupling caps. Bigger caps than the ordinal amp, and 2 of them.

Further to the right is the output low pass filter. Note the 8 shielded inductors and yellow polyethylene filter caps. This indicates a 4 pole filter. Less RF on the output, but how does it sound? Not sure yet. Zobel resistors can just be seen.

At the far right we find the output wire to the speaker terminals.
