Components layout
You need to put all parts correctly on PCB. Even You need to be careful putting the polarity of the electrolytic capacitors and Diodes right ways.
Recommended:
Full wave rectifier diodes
In the component layout, use both full wave rectifier diode that has three lead. For positive has A K A
And negative has K A K lead. It may be an old part. So you can apply two diodes connection as below circuit diagram.
How to install TDA2030
The IC is the final sequence. You should install with a heat sink first. Then, Solder it on PCB. Because of if soldering IC first. The Holes between the ICs and the heat sink may be mismatched.
When all things are complete. Then, connect the speakers to the output. And connect the ACV of transformer current at least of 2A, ACV 12V CT 12V or 15V CT 15V, One or the other to the power connector terminal.
Testing
Our amplifiers are ready to test. We use a finger, touch input on both. It will noise of the hum out of the speakers. That sound is good. Then, use a good quality tone controls. To test the complete sound again.

Friends the given circuit diagram is wrong
What is. Correct way?
Anyone know the proper connections.???.
The problem is on the 2030 chip you have pin 3 and 5 reversed . Pin 1 is + and pin 5 should be on the same side in the schematic. Pin 2 is – and pin 3 should be on the same side in the schematic. Easy mistake
pls give me a 5.2 channel circuit
simple ic transistor based
with power supply
Whis it? In the parts list you show c2,3,4,5,7 as 0.022uf but in the schematic you show them as 0.22uf. There is a big difference. Also in the parts list you have c1 and c6 as 0.0015 uf 50v and 10 uf 16v but the schematic shows them as both 0.22 uf . Can u pleas write me with the correct info? What else is wrong with the project? Help please. I bought all the parts but can’t assemble until I know.
Thank u
Can we use the tda2050 place of tda2030, what watts of that type amp
3# 14W TDA2030 Stereo amplifier circuit
can i use 12 0 12 1A transformer??
no u can not use ….
Hello Akshay,
Thanks for you visit. I like your question.
If you use 12 CT transformer. The output DC voltage will be 17V. It makes output is lower sound than 15V transformer. (21VDC output).
Have a good day.
Thanks
Apichet
how many inch speaker it take load
There is little mistake in the circuit.if the output is 120watts then the power transistor getting DC+ voltage via TDA2030 ? It must be in parallel to 2.2ohms supply. it will not work in 6volt DC. It requires 12V/7Amps free from rippling DC.
TRANSISTOR COLECTOR LEG
yeh… i hav made dis circuit…
the sound quality is nice.
but the bass reflex is very poor..
i replace both TDA2030A IC to TDA2050..
and added one 1mF caps at the (+ve) input signal
and added one 2000mF caps at the output signal..
now the bass and the output power is increased to more… then before it has.
Is this circuit runs well? there is no rectifier in this circuit. so, will this circuit will run connecting 15 volt 2 amp transformer directly to the circuit board?

Me I have problems with the loadline protection for amplifier in circuit
Hey…i want to knw exacly can this curcuit use 2OHM speaker load?coz on explanation above blabla watt reach 200w on 2ohm load..so that mean admin already test it on 2ohm without anyfailure overheating etc??The connection between PIN R4 and R8 2.2k resistor..the line conected like that way?i feel something not right on this schematic,,,U sure r4 & r8 connected that way??
pls dont confuse us on this all things right here..coz if something doesnt right happen our $$$ fly away…maybe cheap on u country but on my country???this chip reach $15.00 each for tda2030 /TDA2030A.power transistor O_O $ 14.00 each so 2 pair = 14×4,,the capasitor for ps also walla..50v/10000uF reach $46.00 each..
I rebuilt the circuit. One of the output tranisistors was blown up. There was also a bit of “Magic smoke”.
I hoped better caracteristics from this circuit.
