Portable lamp flasher with 230V AC power source, it is able high-power incandescent electric lamp flasher.
It is basically a dual flasher (alternating blinker) that can handle two separate 230V AC loads (bulbs L1 and L2). The circuit is fully transistorised and battery-powered. The free-running oscillator circuit is realised using two low-power, low-noise transistors T1 and T2. One of the two transistors is always conducting, while the other is blocking.
Above diagram is the schematic diagram of mono power amplifier which use power IC of STK-1050 as the main component. Build two similar circuit for stereo amplifier circuit.

The following diagram is the schematic diagram of simple and cheap mini amplifier circuit.
The circuit built based SSM2211. I have never heard about this IC before, this IC may be quite difficult to find in the market, so before deciding to make this circuit, you better look for information about availability of this component in the nearest electronics store.
