Need some advice on a tda 2003 audio amplifier.
Hi I've built a mono amplifier based on this schematic: https://www.circuitsdiy.com/tda2003-amplifier-circuit-diagram/
However, when I turn on the supply (a 12v hobby supply) I either get lots of popping or humming and if I can stop that by moving things about the humming persists and the audio plays extremely quietly.
The circuit is currently set up ona breadboard without volume control as I am just prototyping it at the moment. However if I press the chip into the board, occasionally, hi amps will be pulled and melt the supply cables. Any help would be appreciated solving my problem.
Thanks
