So since I'm a complete beginner in electronics I thought I might as well start somewhere and I decided to build a somewhat simple amplifier but some things about the circuit are unclear to me.The amplifier is based on the TDA2030A IC. I chose this amp because I already have the IC at hand. This is the circuit I'm trying to build:
Website
Pics of the circuit and PCB
Datasheet and the same circuit is in the datasheet as an example.
First of all what types of capacitors should I use for C3,C4,C7 and C8. C1,C2,C5 and C6 are obviously electrolytic.
Why are C8 and R5's values not given and they are represented with broken lines?
Can I use a normal PC PSU to power this amp to try it out since PC PSU's have both +/- 5v and ground. (or suggest an unregulated PSU, something simple that I could build.)
Do I connect the ground from the PSU and the negative lead from the speakers and input to the ground plane of the PCB.
How do I control the loudness of the speaker? I don't see a potentiometer anywhere on the circuit so I'm guessing it is to be placed between the speaker and the circuit and if so of what values should the potentiometer be?
Any help is greatly appreciated
