300 WATT NPN DRIVER BOARD FAULT FINDING

अक्सर बहुत सारे लोगों का सर्किट जो वह बनाते हैं फेल हो जाता है और एक बार सर्किट फेल हो गया तो fault ढूंढना बहुत मुश्किल हो जाता है और सब्सक्राइबर उस सर्किट को स्क्रैप में फेंक देता है ! इस वीडियो में आप देखेंगे कि ऐसे ही एक सब्सक्राइबर ने इस सर्किट को बनाया लेकिन उन से ऐसी क्या गलती हो गई जिस वजह से सर्किट Fail हुआ उस सब्सक्राइबर के द्वारा वह सर्किट मुझे बाय पोस्ट भेजा गया और उस सर्किट के फाल्ट को ढूंढ कर इस वीडियो में ठीक किया गया है

99 percent of your videos are helpful for DIYERS. And hobbyist. Thanq for your experience and knowledge sharing 🙏

[@gautam07sharma]

Thank's sir,apka 500w (60volt ka)driver circuit diagram dekh kar bina print ka pcb par banaya.sir, 100% ok circuit bana.thank's.

[@vickypatil3703]

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 😊 😊

[@ashokkumarnishad6351]

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

[@narendravadiya7219]

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.

Nice video 👍
As you said a video on

Thanks for your extraordinary sharing of knowledge .

[@qaisarali97]

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

[@AmplifierWorld]

जरूर बनाएंगे

[@shankarraosongade3587]

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

[@AmplifierWorld]

Thanks, aapka comment mujhe bahut achha laga,

[@samdislva2948]

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 TH-cam but your style is different,you always come with something different ..
Thanks for uploading ...
