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।

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

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 ।

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!!!

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।

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।

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.

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

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.

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!!

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.

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 ...

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 🙏🙏

Very good Design by you with very less distortion and wide frequency range also the components placement are technically correct as well 👍🏼👍🏼

Till now I have seen a lot of circuit diagrams on KZfaq 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.

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. 👍

This amplifier circuit design is next level. especially its bias voltage adjustment is very good.

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...👍

Compact amplifier. Sound quality is also awesome. Nicely explained the connections and tunings to be done for s optimal

Sir you deserve a billion of likes and subscribers . This PCP is just wow.

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,

Baki sab practical bataty h ap vahid insan hh pury KZfaq py Jo etna detail ke sath ek ek cheez samjaty h♥️✨

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👍

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 .

Dear Sir hats off to your intellectual Knowledge... And dedication towards your passion even in the busy schedule of your work 🙏❤️🙏🙏🙏❤️🙏

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🇮🇳

Very good experience to learning with you. Good Effort to making this board Sound quality is really good.

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.

Sir aap itni easy way me samjhate ho Ki koi bachha bhi samjh jaye Or is tarah ki top class knoledge

Theory ek taraf, but practical ka baat hi kuch alag hai, bohot kuch naya Janne ko mila sir, nice keep it on. nice amplifier.

Thank u sir for your valuable information provided to us Thanks for this high quality TTC5200,TTA1943 Amplifier video it is the best circuit among all . I Followed all your videos to my circuits ,powersupply etc. I have a big interest in this field and your videos always improve me. Thank you sir

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 |

Hello sir your dedication towards a great quality sound is next level, you always inspire me, I hope some day this amplifier Board will also be mine, Thank you

Sudhir jee, aap jo bhi banate ho woh zabardast hoga hee. Respect for pure knowledge .

This need proper knowledge as you given in previous videos and i like the way you mount Transistors on heat sink . Nice Work .

Very professionally built amplifier. Great work sir

Small and very good circuit good sound quality. sir keep uploading video your videos teach us many things we learn from you very much your explanation just awesome thank you very much for all video 😊😊😊😊😊😊❤ from kolkata.

Bhut achha amplifier ho gya ye to 😮 Kaash esi quality market producs me bhi hoti 🥺 market me nai milta itna complex circuit 🥺🥺

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 👍

Excellent video. I eagerly wait for your video. Your explanation is superb. Continue the good work. Would love to try and build this amp one day.

It's great and very complicated .. But love how you give a single details..

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

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....

These boards are compact and easy to make frequency response is very good Very detailed videos related to this amp

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

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 for giving this pcb. Small and powerful

Sound quality very good sir Nicely explained each and every short points also

Love From Bangladesh ❤️ Best Channel seen so far for audio related knowledge.

Many after market pcb not this biasing adjustment for low watt output board. Good to see in your design. Your knowledge in by this channel will help lot of sound lovers. Good quality sound also. Keep it up sir...

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...❤️❤️❤️

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 🤤

Very good sir. I am getting a lot of knowledge from you. This amplifier board is awsome.

Really a hi fi class amplifier. Audio is nice in its default sound without bt board. After bt fidelity seems to lost. I also want to try this board. You have provided plenty of detail of this board which is missing on other channels.

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 👍

Sir aapka ye board sabse hatke or sabse achchha hai... Designing superb...

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.....

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.

Thanks for giving us a nice amplifier Circuit for home users

Sir your channel is like a electronic book Thanqu sir for providing valuable information .. Happy republic day

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

क्या बात है वाह सुधीर जी 🙏👍👌

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.

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

Best Compact powerfull amplifier..Great work sir !

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

I love it's wide range of frequencies response 15hz to 30khz ❣️

Sir apki mehnat ko salute karta hoon.

Mai naya hu aur acb bahut jabardast hai. Jo last time volt set kar rahe wo bahut complicated hai. Voice quality super hai.

Best Design Seen so Far Awesome Sir🔥

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

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 KZfaq and helping people like me.

You deserve one word awesome👌. Great presentation👏

Sir aap great teacher ho aapke video se muze help milti he , thanks sir 🙏🏼

Very good Sir, you are making good amplifier board. And your work is very honest.Carry on Sir. I like your work👍

Best audio other any amplifier👍 Sir you are best and I am so happy I have your subscriber

Beautiful PCB You are a good designer

thanks for this valuable amplifier circuit

Sir g bhot hi fine audio h is board ki ikdam noise free this is best

Very good pcb design and nice quality 🙏

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,,❤️❤️❤️❤️

Mere khne pe apne Jo enclosure ke video banaya tha uske liye thankyou ❣️❣️❣️

This is amazing 😍🤩 bass and treble is best for me I want high quality sound for home and normally birthday party. Iska power output acha h jo home use ke liye or chhoti party ke liye enough h. I really want to make this amplifier. Thank you very much sir for introducing this amplifier. You are great sir..

Amazing amplifier design. I am happy that we are now focusing on audiophile designs. Though I would suggest you to buy copyrights for KZfaq of a particular all round song which has all ranges. It could be 10 yr old song for low cost but will be easier to viewers to identify difference in audio quality from a familiar audio track. Thanks for sharing designs.

Best design PCB 100 watt amplifier👍👍

Sir aap na bahut hi badhiya tarike se samjhate hai,ye board bahut achha laga mujhe, Treble bahut hi badhiya hai sir
