Hi friends, in this video I try to make a high power amplifier. This amplifier consists of 2 channels (stereo). Each channel uses 5 pairs of end transistors (2SC5200 & 2SA1943).
In this assembly, I only used a 5A 47VAC transformer. But this amplifier can still be upgraded up to 10A 55VAC (if using the same box). The total budget for this amplifier is around $120.

Couple of observations: 1) Use masking tape to protect painted panel from accidental damage while drilling holes. 2) Use nyloc nuts to secure modules to the chassis. If nyloc nuts are not available use thread-lock blue - Loctite 242 to keep nuts from backing off 3) Always use a wire hook to connect a wire to eyelet :( Do not rely on solder to provide mechanical support.
Beautiful work. Thanks for this.
OMG! The two loud cooling fans adds to the music.
Very cool, great work! 😁
Well built👍👍nice looking amp
Very good looks so professional 👏👏👏👏🇵🇭
Thanks
Super clearty good job sir ❤
Quality build👍
loved it
ha, i saw what you did with the speakon, mounting holes where drilled in mirror, so you needed self tapping screws :) instead of the normal M3 bolts
Nice work, would have chosen a heavier transformer though.
Wow amazing
thank you sir useful video
where did you get the amps from? can't find them anywhere .. would be nice if you included that information thanks
nice work
Kerjanya kemas👍👍
Oh right, an amp that the fan sounds louder than the music, marvellous.
You've never built a solid state amplifier that's obvious. People like you should start with a high voltage vacuum tube amp. Do zero research, maybe you won't live through it.
@@joshpoe Thanks for the advice, appreciated, I will save myself some money and buy something that sounds half decent instead.
@@dougieroberts7045 before you judge maybe you should understand what speakers are being used and how this was recorded. I've listened to 1 million dollar Krell and Mark Levinson systems generating thousands of watts but for musicality I've been more blown away by analog systems running off batteries making less than 50 watts.
That’s fairly average by PA amplifier standards…
@@joshpoe This amplifier is not so powerful to run fans on idle or low load. My Yamaha amplifier turns on fans only on high load.
And good amplifier has to have balanced inputs.
Behtarin luk👍👍👍👍👍
Good Job .... super like amigo..
joss tenan ki power balap
Mantap jga yg ini mas.
Nice power sound system
Joss mase...
Mantap boss👍👍
Veri good
Congratulations 👏
Wow nice amp
NEIGHBORS LOVE IT
Is very good 👍👍
Hi... amazing work
But do you have a component list and a tutorial on how to build the board off the pcb??? For the amp section
Very good
I love it
josss masszeh
Do you have a parts list and vendor information beyond the proto circuit board house? Or are you selling plans?
Excelente proyecto, buen sonido
Felicitaciones
Nice
Perfect!!!
Very very nice
Sangat kreatip sangat rapi seperti power pabrikan,sangat bangga ada orang sulsel bisa begini😊
Thengkyu👌
@@cbzproject itu dijual nda bang
@@cbzproject di jual berapa bang
what kit is this and what features has it? output power ....price brand and so on
สุดยอดเยี่ยม
Muito bom. Da hora.parabens . Eu compraria. Só falta colocar mais LED . Na frente.
I really like this video
Thanks
Great video 👍🏻 Back room amp, not a fan of fans in amplifiers.
Micro boostrap mantap..
Mantap 😀
Mantap mas bro.. 👏👍
Thanks
Orang indo Dengan gaya
👍👍👍👍 good
what are the possibilities of putting in a bass and treble control?
Beautiful work and slowdown your video im a beginner in electronics bro
Im from indonesia i love sulawesi 🙏
Terima kasih sharing vidionya..
Mantap Mirip built up mas salam dari jateng kab.pemalang hadir terus tapi jarang komen
Sipp👌
Mantap👍
Elahhh beli ajaaaa yg pake tabung juga adaa... Udah dolby atmos pulak.... Optical cable to speaker pake velodine
West Sulawesi product🔥
Nice❤👋
nice one sir youre greath and excellent work job.sending my full support of youre compony.god bless.😇😊🙏❤
Amplifier finishing so good voice quality 💕 full amplifier beautiful 🥰
Mantap
nice
좋은영상 잘보고갑니다....
이런것도 가능한가요?
파워 앰프를 인티로 만들어서 마이크도 되고
베이스볼륨과 고음볼륨도되고 셀럭터 스윗치도 달아서 외부입력 1,2,3, 그리고 가능하면 레코드 입력도 되고
전면에는 두개의 아날로구 출력메타를 크게두개 달아서 입체감을주고
PA앰프도 되지만 오디오용으로도 될수있는 멋진앰프도 가능한지 물어봅니다!^^
그리고 펜소리가 안들릴정도로 조용해야됩니다...
love your skill and your Indonesian brother Romadhon work too. Mantap. Love from India.
Super super super 👌
Keren kerjanyah rapih
Good
Sir where you are buying amplifier chassis
Mantap ada logo dri pulau sulawesi
Joooosss mas..
Untuk older siap pakai srti itu lewat apa bang..?
Aku suka karia-kariamu brow👍👍
Sipp👌
Where Do you all get these amp casing from🤔
From where do you buy the cabin?
GOOD WORK BUT HOW MUCH DID IT ALL COST AND HOW MUCH RMS IS IT KICKING OUT
Nice looking amp. I'm a bit worried about lack of protection. I didn't see any fuse on that transformer. Also there should be some inductance to remove noise from line. I also didn't see any fuse on other side of that transformer. But who knows maybe there was some. Anyway. I would suggest to add steel plate from both sides so actual amplifier is shielded from transformer .It might help a little to remove the hum/noise.
the fuse is located in the ac connector socket @4:52
There is a fuse on the power inlet. A noise filer would have been nice, but there is no switchmode stuff and a lot of capacity, so I am sure it is fine.
@@Daaremikkel yes Sorry i did miss that. I'm glad for that also i'm glad for that second fuse on secondary. As you said some filtering would be nice and i'm not sure how effective it would be but i expect it will loose efficiency once higher power will come into play..but still it might be good idea to test it. Could you please make simple check ..Bring proper laboratory 6.5 digit meter and test AC voltage at the input of your power stage..I know you can't check all frequencies only line .but still this might show you how much AC you have in your amplifier..I would also suggest to check it with some load..lets say 400Hz on input with full power and then check it again..
@@SylwerDragon That and adding speaker protection would be a great idea especially given plenty of room inside the chassis. Overall, I think for the advertised budget it's a pretty solid build. Speaker protection would have only added maybe $10-15. At least in this build amp heatsinks are properly installed in line with fan airflow, seen so many in these DIY videos that are installed perpendicular to the airflow.
Makasih atas ilmunya
good project sir nice video how much watts ka amplifier boards used?
Mantapp masss
Sipp👌
Jos jos tanks
Konten kek gini gua like

Where do you tou buy this cabinet?
Your video is very good but where to buy this amplifier why you don't know please enter the link
Is it coming full assembly?
If I want full sets is it possible to send. I am from Pondicherry India
I'm here again, do you have diagram of the amplifier? Thanks from Venezuela.
Mantap ok 👍👍👍
Keerrreeen bosku
Sipp👌
Where can I get that cabinet?
merk trafo ditutup, tp coba saya tebak.. pasti merknya Beii.. 😆
oh ya, sekali kali backsound ny pake tarling mas, biar mantep.. 😀
Invest a couple bucks in an automatic center punch, it will make drilling accurately a lot easier.
Hadir bosku, salam dari sulawesi tenggara
Sipp👌
can I get a parts list from you so I can build one?
Jakut hadir broo
mau tau gaess mixer yang di pakai itu ashley yg model apa ya ?
Very good, congratulations
Thanks
how to buy or purchase item from cbz
Where i' can get 2 amplifiers yo ensambli
Nunggu offlinenya. Akhirnya bisa di dwonload . Wkwkwk
Please give link to purchase this cabinet
Bayya super
