Description
Speaker Delay Circuit
This is a simple speaker delay circuit made with NE555.
It connects to the amplifier output and protects the speakers.
When transferring the relays to the PCB, two were used, unlike the schematic.
This will allow you to use two cheap relays instead of expensive ones.
Tested.
However, there is a small mistake in the PCB diagram.
The transistor marked as BD337 should be BC337.
