Basic TDA2003 or TDA2002 power amplifier. You may use a PCB heat sink. They are essentially the same power amp IC.
Basic TDA2006 power amplifier. You may use a PCB heat sink.
Dual OpAmp board using a single rail supply.
This project is for my 200L water tank I use to replace aquarium water. It monitors water temp and water level when filling. A Level is selected and when the water level reaches that level a buzzer so...

For those rotary switches that are terrible to solder wires too.
Simple power amplifier capable of 2 to 3 Watts. DC supply between 5V - 15V. If you are going to drive it hard consider adding some small 'stickon' heat-sinks to ensure it doesn't get hot.
A simple fullwave rectifier for vacuum tubes. A 100k 2W resistor to keep the capacitors drained. Terminals to add a choke between the caps. 2W10 bridge rectifier, max 1000V, 2A, (PCB is NOT designe...
As expected. Hassle free
Good
Very happy with the result, Thanks
