Hello people, anybody can advice me, I wanna run my power amplifier which take in 24v 3amp, but I am just having a lot of 12v 1.5amp chargers, is there a safe way to combine 2 chargers to make 24v 3amps?
Why are you running an amplifier from a charger? I don't think they were designed for that purpose.Hello people, anybody can advice me, I wanna run my power amplifier which take in 24v 3amp, but I am just having a lot of 12v 1.5amp chargers, is there a safe way to combine 2 chargers to make 24v 3amps?
You did not answer the question I asked. You answered another question that I already knew the answer to.I do amplifier myself and it can run 12v -24v, but 12v its too weak.
If that is the only thing available, then you have your answer. Why do you even have to ask the question?That is only the source of power easily available bro. or advice me, how can I powering my amp?
Oh, sometime I don't trust YouTube stuff. I did the same amplifier with tripple IRFZ44N then my speakers started to heat upYour Amplifire is not an audio amplifier:
1) Its 700V 13003 transistor is not biased correctly.
2) It needs many output transistors because it is a class-A heater that heats a lot all the time even when it is not playing.
3) It uses a plus 25V and a negative 25V power supply. The negative power supply has an orange wire.
4) The speaker has a high DC current in it which will quickly burn it out.
Many student kids from a country with billions of people post horrible electronic circuits on You Tube that do not work properly. They do it to get paid by You Tube each time somebody looks at the ad ahead of their video.Oh, sometime I don't trust YouTube stuff.

OK I see, is there a way I can use a transformer without center-tapped on this schematic diagram? and can I use even soft iron transformer?Many student kids from a country with billions of people post horrible electronic circuits on You Tube that do not work properly.

If you have FOUR supplies, each able to deliver 12 volts at 1.5 amps, then you put two sets of two in series all in parallel and that will add up to 24 volts and 3 amps capability. BUT before any of that you need to use a voltmeter to verify that the voltage from each supply is actually 12 volts. That is because if they are chargers then the voltage must be greater than 12 volts. BUT the circuit shown in post #7 can not ever work no matter what because the circuit is all wrong. AND certainly the speaker will heat up and burn out because there is DC in the coil all the time. I would not ever trust a circuit from you-tube. Look at the circuits posted on a technical website, , such as "schematicforfree" or the "Free information society" websites. On those sites you will find circuits that will work.If that is the only thing available, then you have your answer. why do you even have to ask the question?
And I'm not your "bro"!

A switching mode supply is a quite complex system, and not a project for a beginner, or an intermediate. And a rectifier,filter, regulator system does not need a circuit board, it can be assembled on a couple of solder lug terminal strips.getting harder to find the transformers for linear power supply

The rectifier/filter board is'nt cheap either

some say switch mode power supply will work
First, nobody has suggested complexity. Series and parallel connections like I described are not complex.The overall situation requires overcoming complexity. Too complex for the average DIY.
The specific situation is 24V 4A for stereo.
The question about joining two 12-0-12 transformers was yes it is possibly to get 24V.
The discussion goes silent because of liability and safety. As a result of shortage. The shortage is a result of balanced trade and fair trade without having strings attached that threaten soverienty.
