I ordered a very simple Guitar Amplifier PCB kit. It's a TDA2030 Audio Amplifier, a TL071 JFET-input op amp, with a bunch of caps and resistors.
I soldered everything up, and I was reading the online instructions. This is the kit, by the way. In the Description of this kit, it says the following about Power Supply:
The operating voltage is 12vdc. It has two 1000uF Capacitors on the input power for additional filtering. You will need a 12vdc power supply capable of delivering at least 2 amps, a 20-watt or better power supply will work just fine.
I was going to buy a new "wall wart" 12V power supply on Amazon, but then I remembered that I already have a "laptop style" 12V power supply that I bought to power a big LED project a few years ago. This power supply says...
Input: 100 - 240VAC - 50/60 Hz, 2.7A
Output: 12V === 10000mA
This may all be perfectly obvious to you guys... but... will a power supply that has an output of 10000mA safely power a circuit that needs a power supply, "capable of delivering at least 2 amps?" First off... 10000 mA is 10 Amps... right? Is the idea that this power supply can deliver "up to 10 Amps"... but this little amp circuit will only "draw" what it needs?
