This is the Project of  Simple IC TDA2030 Complete tone Control Circuit Diagram. This circuit that use IC TDA2030, but this series is equipped with a tone control. Tone controls include Bass, Treble, and Volume. Power amplifier and tone control has been put together in a single PCB. This amplifier is a mono amplifier type, can be modify for guitar amplifiers .  If not coupled amplifier (mic preamp) then you must deactivated potensio treble and bass, why? because if not using a mic preamp and still maintain potensio treble and bass sound input (input) from the guitar will not or the maximum discharge is not tight on the speakers . So you must deactivated a way to decide which directly connected capacitor  with the tone control circuit, and capacitor were connected directly to potensio volume and input jack.   TDA2030 Complete Tone Control Circuit Diagram PCB Layout   TDA2030 Complete Tone Control Circuit Diagram PCB

Simple Tone Control Circuit Diagram TDA2030. This is a best tone circuit with TDA2030, Tone controls include Bass, Treebel, and Volume. Power amplifier and tone control has been put together in a single PCB. As well as its power supply circuit was also used as one with the power amp, and tone control. Making it easier in the installation and will look neat.  Simple Tone Control Circuit Diagram PCB Layout  PCB Design This amplifier is a mono amplifier type, can be modif for guitar amplifiers.

This is a 200 Watt Amplifier Circuit Diagram that uses a TDA2030 IC which is an audio power amplifier 200 watt low cost. The 200 watts can be achieved with a load impedance of 4 ohms. The TDA2030 can typically provide up to 14 watts into a 4 ohm load, but if used in bridge mode and we use some cheap power transistors we can get to 200 watt. The design of this amplifier circuit 200 watt audio is very simple and requires few external components. For best performance, you can use a source of 28 volts (+ / - 14 volts), not more than 44 volts (+ / - 20 volts).  As you can see in the diagram, for this power amplifier circuit you need high capacity capacitors and a power supply high current. All transistors and ICS should be mounted on a heat sink to prevent damage by temperature. For small value resistors (1 ohm, 2.2 ohm) resistors use 2-5 watts.  200 Watt Amplifier Circuit Diagram using TDA2030
