These are 4 simple 50w OTL audio amplifier circuits using 2N3055 as main parts. We can build easy and cheap. It’s durable and very loud sound, Not needed speaker Protection. We use all transistors and LM3900 below.
Easy 50 watt audio Amplifier circuit OTL using 2N3055
If you are seeking power Amplifier at the loud good sound, durable and economize. We recommend the 50 watt audio amplifier circuit using 2N3055. Because, it use the equipment that seek good easy and build not difficult with. Many you who tell amp OTL the sound is not good. Me chest edge that be not the loud sound is excellent.
Then like to use general ( in the past ) although in contain divide still have use. I like it fining decorates the circuit.
Just you feed power supply 50V 2A also the work has already and a loudspeaker should use 8ohm 12 inc. sizes. Besides still model PCB for the convenience of friends. Request have fun Power Amplifier OTL 50Watt , please sir.
Some friend need 50w car amplifier circuit
60 watt/ 50 watt audio amplifier circuit with PCB using 2N3055
This is Power Amplifier OTL 60W circuit. It is the circuit that gives bland excellent sound, because of using the transistor entirely (Hot part 2N3055 x 2) have no IC mix. Then may build difficult go to small but for what is the experienced person may have no a problem. For the sound power that pay to come out about 60W at 8ohm size loudspeakers s build to sing can bail 12-inch sizes comfortable. About story of the voltage supply for this circuit as a result of the important. Should use the pressure about 30V the trend doesn’t lower 3A. Other details see in circuit picture.
Next ideal be take LM3900 as differential IC so easy circuit to build.
50 watts/ OTL Power Amplifier circuit using LM3900, 2N3055
This be power amp OTL 50Watt use IC LM3900 and 2N3055 x 3pcs transistors to pillar equipment. Follow very circuit keeps to are Class ab then have a voice good loud. When , be amp OTL you then are certain that build easy use power supply the group is one 70V sizes by must use Current low 2Amp go up. Then have a voice good another thing you will like that amplifier. This durability do not make a loudspeaker a lose easy. The detail is other see in the circuit and model PCB next.
We like a 2N3055 Power Amplifier Circuit. Although it is the very ancient transistors, but it still have a lot of classic and very good sound. It is popular forever, very cheap, easy to find, easy to use. We recommended the 2N3055 power amplifiers circuit with PCB list below!
If you want to create the integrated power amplifier project for the first time.In addition, we will use ICs because It’s convenient and modern. But I often recommend this project 2N3055 amplifier circuit. The output power is 30 watts RMS, using all transistors. You may like it.
40W to 55W transistors audio amplifier
This circuit is one that stands out for ages over 40 years, with sound quality that is hard to find compared be other circuits. If you experimental build or ask people who try already built. Will believe that this is not as exaggerated statement more than true.
50W OCL main amplifier using LF351-2N3055-MJ2955 with PCB
This 50W OCL main amplifier circuit has high quality,economical and also easy to build too. Because it is designed simple, It can be easily created in your friends, An electronics rookie. And cheap when compared to other speakers, the as same volume level.
Power Amplifier OCL 70 watts using IC-741, 2N3055
It is Main Power Amplifier Circuit 70Watt RMS sizes are model OCL Class AB. Use pillar equipment be IC 741 and Transistor 2N3055,MJ2955 a little this equipment circuit. If friends want get electric tall power about 70Watt should use Voltage Supply +38V , […]
Integrated power amplifier OTL 35w by 2N3055
If you want build power amplifier that low watts and easy to builds. We recommended this circuit because it is OTL use single power and without the speaker protection circuit.
If you are looking for a 100-watt OTL amplifier circuit, For the job a small PA system, The news spread in the village or the sound system for the conference. I recommend this circuit, Because sound is very loud. When compared to other circuits at power are equal and very durable.
