Sir aapke sabhi circuit perfect hai .. Maine bnaye hue circuit sabhi success hue hai ..or kuch problem aa bhi gyi to wo aapne solve kr diye.. you are great sir ..thank you so much 😊 😊

इस तरह के वीडीयो बहुत ही कम है यु टयुब पर बहुत ही बेहतरीन वीडीयो है सर फाल्ट का वीडीयो भी बना कर डाला करे सर बहुत कुछ सीखने को मीलता है धन्यवाद इतना अँछा वीडीयो के लिए

For successful d.i.y.a good p.c.b.,best components and precise soldering are menditory.Without good soldering,no one can achieve success. Thank you sir.Your teaching power is good. I like your method for fault findings.

Sir bahut helpful tha...🙏 Time ki bachat ho jati hai sahi trick lagane se

बहुत शानदार भाई साब,, जो आपने सच्चे मन से, hr फाल्ट को समझाया हैं,, इससे क्या होगा कि जो नए नए बंदे हैं उन्हें बहुत अच्छा मार्ग दर्शन मिलेगा, और आप की साफ नीयत से सिखाने की प्रवर्ति से उनका भला होगा, जो वो आपको दुआए देंगे, वो बहुत अनमोल हैं, many many thanks,, उमीद krta हूँ आप भविष्य में bhi इसी तरहा sb का भला करते रहेंगे, जय हिंद जय भारत

Sir ap bohot hi asan tarike se samzate ho video dekh kar maza aa jata hai

Sir aapne commit kiya tha npn hi watts ke circuite banayenge aur agar class H NPN me bana den to lajawab hoga,mai aapka kai videos download kar liya hun akshar sunta hun aur chek bhi karta hun kuchh naya aaya ke nahI, aapka sikhane ka tariqua bahut achha hai aap circuit draw karte hain satha satha batate aapka maqusad hota hai sahi me sikhane ka Best of luck mai 61 cross kar chuka hun mera profession cinema hall ka sound system aur Projector ka tha abhi bhi aap jaise teacher se kuchh sikhta hun aur phir kuchh kuchh bana ne laga hun

Very good sir. Up bahut great hao

Yes you are right,these are common errors in DIY pcb 's.. This was also great video, Please please make vedio on soldering as well.. some times connecting wires(connection between driver board and output transistors) are made using fine aluminium strands,are hard to solder !!! The person who made this circuit board had used excess of soldering wire...so please make vedio on soldering also that will be very helpful.. No doubt we get many many such vedios on RU-vid but your style is different,you always come with something different .. Thanks for uploading ...

Mene ye circuit board banaye tha or bahut achcha kam kr raha hai

Nice video 👍 As you said a video on Feed back and bias and couplling ideas for hi.bass. or. . hi.mid transistor amplifier . Thanks for your extraordinary sharing of knowledge .

Very nice and helpful video.

Namaskar Sar ji aapka to baat alag hai aap bahut samjha kar kam Karte Hain

Very good sir ji

Best circuit performance is more than expection one thing I want to confirm that which type of Bess treble circuit will good for this means IC based or transistor based

Namaste Sirji, Standby aur Mute kaise upyog karein batayega. Short circuit protection, thermal shutdown ka ek video dikhaye, sirf jankari ke liye. Aapka lecture in professional way jari rakhiye. Sun ne mein maza aur interest aata hai.

Namaskar sar main pahle bhi 4 5 bar request aapko bheja tha ki power amplifier ke Panch production Jo aapane Baat Aaye The Unka circuit diagram tatha unke bare mein detail ka video ke bare mein Kaha Tha aapane Kaha Tha ki lockdown ke bad Mein is video ko Banaunga to upload Karunga Sar is video ko jald se jald banaa Aisa rahata ki Hamari knowledge mein ijaafa ho sake aapka bahut bahut Dhanyavad sar
