मैंने कई तरह के स्कीमैटिक ड्राइंग को लेकर पीसीबी डिज़ाइन करके एम्पलीफायर बोर्ड बनाये है और वो मार्किट में सुपरहिट चल भी रहे है, क्योकि मार्केट में लोगो को हाई बास एंड ट्रेबल ही चाहिए होता है। लेकिन मेरे कुछ म्यूजिशियन दोस्त है उनकी कसौटी पर मेरे द्वारा बनाया बोर्ड और मार्किट में मिलनेवाला बोर्ड भी खरा नही उतरा। उनका कहना है कि एम्पलीफायर ऐसा होना चाहिए जो कि हमारे द्वारा बजाई गई ट्यून को बिल्कुल उसी तरह से रिप्रोडूस करे जैसा हमने ट्यून बनाई है। जैसे कि स्टूडियो मॉनीटर्स में साउंड रिप्रोडूस होता है। और कितने भी वाट का एम्पलीफायर क्यो ना हो उसमे ईयरफ़ोन का ऑप्शन होना चाहिए। क्योंकि ईयरफ़ोन पर साउंड क्वालिटी, हमिंग, नॉइज़, तुरंत समझ आती है।
अब मुझे लगता है कि आपका बोर्ड उन लोगो की अपेक्षाओं पर खरा उतर सकता है।
बहोतसे amplifier same tune मै ऑडियो reproduce करसकते है | अच्छे स्पीकर इस्तेमाल करके देखो |
Sir 'bise' voltage kitna hona chaiye best sound ke liye
Sir ( Sailender yadav )aap k duara banaye gaye circuits bahut badiya hotae hain. Rahi baat audio quality ki, agar us k sath achi quality ki bass treble lagai Jaye toh audio quality b bahut badiya niklti hai
Aapne ekdam sahi likha hai
Aapka disign bahot accha laga mughe mai aapke sab videos dekta hu from Bombay Basha
Pehla indian sakhs aisa dekha hai jisko itni deep level pe knowledge hai sound system ke baare me
Kash kabhi apse mil pata aur kuchh doubt aur questions k answer le pata
Thanks
Consideration & Problems.
Consideration- 1. Stability components are good enough.
2. DC offset voltage is excellent by the help of differential amplifier pair matching.
3. Bias stability is well balanced for the thermal tracking of the bias transistor.
Problems- 1. Collector out is difficult in desghine .if any problem happens transistor will be damaged.
2. Frequency response is little bit short I had thinked it will cover 10Hz to 100khz.
3. Need more balanced constant current for VAS stage for stability.. thank you. Overall its lot better desghine than market one . All the best.
Great observation
Sir, well explained, can you supply one full kit with heatsink please let me know the amount.
Not everyone shares all knowledge. But you share all you knowledge to your viewers. Addicted to your videos and following your circuit to make make amplifiers. Thank you 🙏. Bring us more on budget amplifier boards and videos on 5.1 prologic and amplifier.
The best thing, I have liked that it's fully compact, well designed and high-end finishing!
There are many circuits available in market, but What makes this different from local circuits is it's designing, specially in the part of thermally coupled driver Transistor! and proper biasing. Really local manufacturers don't consider this often, which need to be considered!
Besides, the pcb quality is really fantastic as expected from jlc pcb.
The output sound quality is very sweet, soothing and crisp. Every ends of tune are responsing clearly. This makes your circuit different from others! Best wishes for upcoming designs! ♥️
मैंने बहुत सारे अंग्रेजी audio experts की वीडियो देखी है परंतु हिंदी में उस दर्जे का video मैंने शायद पहली बार देखा है । कमाल का video था आपका, सारी जानकारी तो नहीं कह सकता परन्तू amplifier के लिए जो न्यूनतम जानकारी होनी चाहिए वह इस वीडियो के माध्यम से प्राप्त हो गया । मैंने आपकी दूसरी videos भी देखी है, आपकी videos थोड़ी लंबी होती है लेकिन उन्हें बहुत ज्यादा content होता है, जिसे चाह कर भी skip नहीं कर सकते । ऐसे और भी videos लाते रहीए । धन्यवाद श्रीमान ।
सच कहा आपने की इसको बनाना आसान नहीं है लेकिन आपके #समझाने का तरीका इतना आसान है कि बनाने का मन कर रहा है🤔
आवाज भी अच्छा लग रहा है।
Maine aaj tak itna saaf awaj aur clear bit kisi bhi amplifier me nahi suna he main lagbhag Twenty20 years se audio amplifier assemble kar raha hoon. Dexa amplifier ke baad aaj is board me sunne ko mila.super quality ki aawaz hai is board me. My name is TARUN Mukherjee. Thanks. Sir ji.
I seen your all video in all video such a very good professional knowledge about electronics amplifier , following your video guideline I have made many such amplifier in zero PCB,,❤️❤️❤️❤️
Somebody gifted me this PCB last month. As I started to build it I realized its a copy of Rod Eliots P3A. At least give him credit for donating this design to the DIY community. VASP is also selling a copy of this. Plan is to build all 3 types and compare. Noise and output.
You will get better performance and quality if you use a LED like Rod did in his original design.
I once tried to design using darlington pair but probably I made mistake of doing it on General purpose board and it ended up with lot of noise issue. Now I understand how important it is to have right PCB design specially for quiscent amplifier.
Best part of this design is adjustable bias provision.
👍
Bro m 10 sal sy audio amplifier lover hu jb m chota tha tb maine sbse pehle 4440 syno ka boad dekha jaise jaise bda hua tb masters ho gyi audio amplifier ki
आप के समझाने का तरीका बहुत ही यूनिक है।
आप के vedio देखने के बाद से ऑडियो में दिलचस्पी कुछ और गहरी हो गई।
आप ने जितना मर्गदर्शन किया इसके लिए बहु बहुत धन्यवाद।
Sir,
mai aisa ek board khud se assembly karna chata hu lekin PCB nahi hone ke bajese bana nahi pa raha ap agar mujhe PCB diye toh mai bana payunga aur apka bohot abhari rahunga.
Thank you sir is video ke liye.
Haven't seen a video with such crystal clear technical (and accurate) discription. Very few amp modules are available with carefully designed audio path and consideration for noise and distortion.
Very professionally presented!!!
VASP electronics provide those type of boards with low price range
200 watt hifi mono is well built board ...
Few changes in components it will definitely entry level audiophile
आपके समझनेके तरीकेसे आपका ज्ञानभी अच्छा है ये समझ आता है | मै 8 इंच 80 watt स्पीकर design कर रहा हूँ | जिसका frequency रेंज 50-55 Hz से शुरू होगा | और उसमे demodulation रिंग है | जोकि high end स्पीकर मै यूज़ होते है | उसके साथ ये amplifier board में इस्तिमाल करके देखना चाहूँगा |
Sir aap itni easy way me samjhate ho
Ki koi bachha bhi samjh jaye
Or is tarah ki top class knoledge
sir aap ka circuit bhut acha hi es me input limiter circuit lagaya hota to maja ata aap ke hr ak vidio me bhut dhyn se dekhta hu aap ne kaphi kuch sikaya hi app ko coti coti prnam dhnyoad आप के vedio देखने के बाद से ऑडियो में दिलचस्पी कुछ और गहरी हो गई।
Till now I have seen a lot of circuit diagrams on UA-cam and made it, in some I have succeeded and in some I have failed, in others I have not liked quality. Tried a lot and spent money like water. But not now I know about amplifier and now I will never waste my money without full proof. With the help of Sudhir Sir, I have developed a great interest in the field of audio. I have been waiting for this amplifier for many days and today that day dawned. Finally I look at the quality of this board And fully Impressed and I really liked this board.
Baki sab practical bataty h ap vahid insan hh pury UA-cam py Jo etna detail ke sath ek ek cheez samjaty h♥️✨
क्या बात है वाह सुधीर जी
🙏👍👌
Frequency response ⚡20Hz to 30 KHz 🤩👍...Great project...Each and every single steps are explained very well. I was a fan of LM 3886 but now I will check this amplifier board (after you give away one board to me 😅 ) and will share my experience...Thank you for your efforts to enhance our knowledge...👍
LM3886 still is better option
Circuit explanation was good and best part is that the components easily available in market and it is good to beginner as well as professional .
It is sufficient knowledge to non electronics background person to know each step working.
Sir you are genius , sir I want to become like you and work like a professional just because I am love with audio electronics ❤️🥺. You are my inspiration and genius keep growing sir 🤎🤗.
He's legend 💕
Har Koi To No. 1 Bol Raha H, Lekin Ye Bord K Sath To Aap Bhi No. 1 Ho Sir Best Circuit Design H Aur Mujhe Chahiye Bhi Tha....
Bhut achha amplifier ho gya ye to 😮
Kaash esi quality market producs me bhi hoti 🥺 market me nai milta itna complex circuit 🥺🥺
Boht hi acha laga ki itne compact size main itna acha amplifier Design kia hai 😊... And with features like we normally don't see in indian amplifier👍
Sir hamne 7294ka use kiya hai jiska frequency response 20-20000hz tha .par is board ka frequency 15-30000hz hai to ye quality ke hisab se 7294 se bahut achha hai.dhanyabad is type ke amplifier board banane ke liye.sunkar bahut hi shandar laga sound quality
Sir apki video dekh kr bhot achi information milti h sath hi apne 2sc5200 or a1943 ka ik pair me hi 100 watt ka best gain best quality best inpidence matching 💖 krke best amplifier banay bhot Acha bana h hamko bhi buy krna hai ik pcb
I saw in many circuit thermocoupling, this is the first time i could understand why thermocoupling of two transistor is done
I learn always from your video, i learnt seeing basic data sheet. Great job done, i feel i could have fraction of knowledge like you
One more thing is that the pcb is very compact with perfectly placed components .
No one explain why is necessary to match the input transistors and why they should keep as close as possible .
You have great talent to explain the matter perfectly .
Best wishes for you brother ...
Mai naya hu aur acb bahut jabardast hai. Jo last time volt set kar rahe wo bahut complicated hai. Voice quality super hai.
Sir main fact of classAB amplifier's is this is easily repairable than others modern updated amplifiers
And also classAB amplifier provide very beautiful and sweet sounds
Sir I watch your videos regularly,I am a speaker mechanic by proffesion and making amplifiers for myself is my hobby ,I am very thankful to you. For your guidance,

@@shreeyansmohapatra3405 I
This comment not for giveway.....really I like your video and diagrams . Some other channel video is not explanation like you.... you are great sir..... jay hind sir
Class AB amplifier 2sc5200 ,2sc1943 give very clear audio and efficient than class A amplifier class AB have efficiency of 70 to 80% and it professional or home audio and your pcb design is very good ❤️
Thank you sir for sharing the technical knowledge. Sound quality of your PCB is awesome.
I'm always use the blank PCB of VASP Electronic of BJT amplifier. Because I have never satisfied with the ready-made PCB of the market. They always mount the heavy driver transistor more than needs to showing the brightness of the PCB.
I'm always use BD139 & BD140 of CDIL and keep the bias voltage at 0.700 DC by adjusting the 2k p-set of the circuit. But I never checked the D.C offset voltage of the speaker line. After watching your video I have measured the DC offset voltage of my Circuit. It shows aprox 85 m. Volt. There are no way to reduce or adjust the DC offset voltage on the PCB of VASP Electronic.
But as per the knowledge from you, the DC offset voltage may go aprox 150 m. Volt.
So, I am satisfied and thank you once again to sharing the best knowledge.
Yess 👍
Especially i like this board
200 watt hifi mono ..... Vary well build .....
Vary good combination of power and vas transistors ....
Pre assembled me kuch components low quality hai ...... But itna hi problem hai
BD 140 / 139 is good getting up to 120 watt power from board .....
Hi sir I am trying to build this board but due to improper knowledge i have lost my lot of money but know with the help of this video I am very clear with the circuit and terms thank you
Best design PCB 100 watt amplifier👍👍
Thank you so much for explaining and showing coupling and biasing Technics in simple terms. I am using complete PCB for 5200 & 1943 complementary pairs from local manufacturers but too much of power and ambient noises creeping in the Audio path, which I am sure is due to badly designed pcb, also oscillation s in the outputs due bad coupling and bias filtering adjustments. Your video explains all those in clear and simple terms and your project seems to be very well designed and having crystal sound quality wich most of us audio and electronic enthusiasts are searching for. Hope to use your design very soon. Thank you for such informative and enjoyable video. Always take great pleasure and get learning oppertunity 🙏🙏
I am really proud of you.I am try to make this type of amplifier PCB. But can't success. but your videos has help me a lot. ordering a PCB is not possible for me so, I will try to make without PCB.
Thank you sir your are GREAT 🤤
Is taraha ki designing maine abhi tak nhi dekhi khas taur pe transistors ki thermal coupling karna bahut hi shandar idea hai gain ko auto adjust karne k liye. Best design pcb hai sai apka.
Thanks sir. Me ap ko projects ko blank PCB pr banata hu, op amp, subwoofer bass filter,lm3886,7294 ye sab banya hai ap ki help se.. you are a great teacher sir
Thank you sir
Maine bahut se sound test sune hai
Pehli baar kisi indian youtuber ke design ke board ka sound test mujhe acha laga thank you sir once again
You're the best Indian sound youtuber!!
नमस्कार जी 🙏, आपका बहुत बहुत धन्यवाद, जो आपने हमे ऑडियो फाइल एम्प्लीफायर के महत्वपूर्ण पॉइंट्स के बारे में जानकारी दी।
INSHALLAH yaqeenan yh bohat he kamal ka hoga.... Ap ka shoq hai yh or jo chez shoq sy banai jayee wo to best he ho sakti h.....
Dear Sir hats off to your intellectual Knowledge... And dedication towards your passion even in the busy schedule of your work 🙏❤️🙏🙏🙏❤️🙏
I started building amplifiers after watching your videos. I never thought it was possible to do it yourself. Thanks so much.
Bro how can I get the board?

Mujhe lagta hain this amplifier ki sound quality bohot sweet hoga
I am from Bangladesh love you brother
Ye jo amplifier hai iska audio output bhot hi jyaada saandar hai ....... Plus isske pehle jo aapne wuzhi audio ka review diya tha mujhe ye usse bhi jyaada batter laga ........
And sir I humble request to you......I'm a very poor but I'm always interested in amplifiers and electronics....... Love u sir ..... Special thax for u and your knowledge...❤️❤️❤️
This need proper knowledge as you given in previous videos and i like the way you mount Transistors on heat sink . Nice Work .
Hi sir....
First of all thank you so much.....
And I bow my head near you,by considering you as my teacher.
Sir i don't know I get these PCB in your give away or not.
But i comment for my enthusiasm and curiosity in electronics and audio world.
Sir about this amplifier it's amazing and best in audio world,because CLASS AB audio amplifier are their own identity.
Sir your making process is too simple,and making people understand what you trying to create and design is something out of imagine.
You teach us like a mother teach her children.
Sir i am a hungry person of electronic and technical knowledge.Your videos some how calm my madness about all these electronic things.
Thank you sir.
ABOUT THIS DIY AMPLIFIER;
1. BEST SOUN QUALITY
2. BEST DESIGN
3. DETAILING ABOUT ALL THE TRANSISTOR,WHY YOU USED AND WHERE TO USED
4. SOUNDS ARE FLAT, MEAN ONE CAN EASILY CAUGHT EVERY TYPE FREQUENCY RANGE
5. COMPONENT ASSEMBLING IS NEAT AND CLEAN
6. TESTING GUIDE BY YOU IS SOMETHING REMARKABLE
7. AND MAIN POINT NOT HIDING ANY POINT,WHICH MAXIMUM CREATOR DO IN THEIR VIDEOS.....YOU TEACH AND DETAILED EVERY POINT THIS THING IS SUPER.
8. PEOPLE USE DIFFERENT COMPONENT,BUT NOT GIVE ANY REQUIRED KNOWLEDGE...BUT YOU TELL THE REASON AND THEIR REPLACEABLE ANOTHER COMPONENT DETAILS TOO.
9. OVERALL MAKING PROCESS IS BEST EVER BY YOU THAN OTHERS.
10. KEEPING 3 BD TRANSISTOR IN A SINGLE ROW SOMETHING MASTER CLASS.
11. AND LOOK OVER THE HEATING ISSUE IS REMARKABLE.
12. YOUR DIY MONITOR SPEAKER BOX AND TODAY DIY AMPLIFIER & THEIR COMBINATION AND MUSIC A BESTEST TREAT TO WATCHING.
AND FINALLY.....
I have so many questions noted down to ask you.
Tq sir for being a creator in UA-cam and helping people like me.
5200&1943 board very nice
Dekhne Se Hi Lag Gaya ki Amplifier me bahut Achcha sound Aane Wala Hai
I love your videos i made amplifier for my brother which work great..... Great video sir ✨✨✨if this amplifier is of grade AB it work great sir 👍
Awesome Audio 😍Output very smartly designed compact pcb and 0% noise and the best thing is plenty of options of output transistors. ✌️👏👏👏 Great work Sir, Maine apke design se 5.25" woofer ka enclosure banaya tha aur usse jo output mila aaj tak kisi aur enclosure se nhi mila thanks 👍
Yess bro 👍 ......
Yess u can change output transistors ....
But needs some biasing changes
And VAS transistors
With use of MJL serie power transistors you can make 100 % audiophile amplifier
Real world ulta low distortion ... 😀
Bhai 24 0 24 se a calega?
hi sir
nice design and colour and it is easy to fit and small cabin i seen video it good explanation about amplifier nice bass for small room.
plz pick my comment and choose me winner i want have this stereo amplifier.
thanks
Sir you deserve a billion of likes and subscribers .
This PCP is just wow.
Sir aapka ye board sabse hatke or sabse achchha hai... Designing superb...
Sir aap kitna dhyan rakh kar board banata hai who bhi 100 watt me kya baat hai lage raho sir
Bhai kafi time se soch raha tha ki mein aisa koi high power amplifier banao..per proper guidance nahi ho raha tha.... Aapne meri muskil aasan kardi.... apki video dekh ke Josh bhar jata hai kuch naya karne ka... aap such mein ek inspiration ho hum jaiso ke liye Thanks for this DIY project with TTC5200 TTA1943...Happy Republic Day🇮🇳
Sir apke circuit normal circuit s alag hote h, apke circuit high gain dete h, mene gain circuit banaya h jrc5532 use kr k jo bht acha perform bhi kr rha h, per sensitive bht he thodi si bhi mistake s noise bht jldi a jata h, bo video bht useful rha, us s mene PA amplifier mic circuit banaya jo Ahuja amplifier ki takkar ka h, mene 50 rupe m PA mic circuit bna liya, jo pure market m available ni h
Really a great video indeed , with proper explanation .
You are absolutely an experienced person with a excellent knowledge of audio amplifier .
Best of luck brother for your next project ....
All the best wishes from kolkata .
Sir. Very nice pcb design hai .is amplifier ko jitna der chahe utna der chala sakte hai.ye amplifier 8ohm pe 100watt deta hai to 4ohm pe kitna watt dega?
Aur kya ye 2ohm support karega ya nahi.
Sir app ka khud ka banya bord me kami nahi ho sakti. Mai appki sabi videos bhot bariki se dakhna hu. Eslya mai 100% gurenty se bolta hu
Best module as it's made with our efforts and these compounds aren't smd so these are long lasting
Great video with great dedication. A unique and compact design. All the components are within the required rating and nothing is over rated. Best part is the way you mount the input stage not only so close but applied compound paste and sealed them with heat sleave that's impressive moreover the two trimmers used in here are sealed multiturn type that free from corrosion and dust wile gives absolute tuning of biasing and offset voltages.
Sudhir jee, aap jo bhi banate ho woh zabardast hoga hee. Respect for pure knowledge .
Last one year I was planning to make a stereo amplifier for myself, and for that I have almost browse every indian youtube channel. And, I was confused what to do until I subscribed your channel. You have explained everything in detail about hi-fi audio.
I thought I shall make a LM3886, but I just love this one.
This is what I was looking for.
Great.
Also suggest the machine BT for this. Thanks a lot.
Sound quality very good sir
Nicely explained each and every short points also
ham kal se apki video ana ka wait krre the a hi gai video
Sir kya bole hum App Neto Kamal ki jadui dising ki hai Kamal to ye hai ke agar comments padhne mai hy book banayegi
