Power Amplifier with TDA2050

This is not an ordinary project, but an attempt to make a PCB that is suitable for TDA2050 and LM1875 and has all the necessary circuitry on board - power supply, speaker protection,  delayed turn-on and fast turn-off. This is achieved using the convenient uPC1237 IC.

Speaker protection with uPC1237

I was using IC uPC1237 for speaker protection in almost all my power amplifiers, because schematic is very easy to build with few external components.
