सर, मैं Dr हूं लेकिन आपके विडियो देखकर, इलेक्ट्रानिक सवार हो जाता है, 10th class में था तब शौकिया सीखता था, आप से थोड़ा ज्ञान लेकर, 5.1 amp बनाया है। खुशी हुई है धन्यवाद आपका 🙏🏻 यादें ताज़ा हुई
8:40 if want to use blue led of 3V, then pl use 1k ohm resistance @R31. otherwise that R16 collector resistance need to be changed. 🔄 or use 3 diodes, instead of 2. ✌
I am going to build this board with all prescribed components given by the manufacturer, do you suggest any alteration of components that can give better performance ?
Vasp k is board ko leke kayi youtubers ne video banayi hai, is board mein shuru se hi same problem hai. But ye company bas selling mein believe karti hai, after sales service 0 hai
Sir ab apple jitni kimat charge krke very high service de de toa thik hai. But fir yh diy nhi rh jata. Low cost diy is never for novices. These boards are for assemblers and knowledgeable people. That is why they give circuit diagram and full repair facility unlike apple. So do not criticise. This is not for you. So do not criticise the company. This is different selling model.
@@manmeetjammu dear Mr Dalal/Dalle, I am very well verse with what kind of model this crap is following and how they operate. I am their customer as well, and they have done numerous blunders with my several orders. And before advocating about the 'model', get your facts checked and get educated about what a business is. It is not only about selling, it is all about product and after sales service 🤙🏻
@@AmplifierWorld why would I be angry? I am not angry at all, I am just replying based on what I have faced, but a few people take user experience as criticism as they don't have the balls to listen to the other side of story and they get offended
@@cocococololololo i have bought 5000 worth of boards. If I am not satisfied I wont buy. Why have several orders. It can be said you are competitors who is anti dalaee and dallal of this company too. You donot have the understanding of diy model. There is no after sale service. Be it Robo.in or big tech component supplier. You are simply a customer not a DIY ER. It is the skill of the diyer makes the product work. You may have to modify the circuit as If you hVe the knowledge of the circuit. You basically have none. So you call the company. And he responds as I have talked to him 2 years ago. He tells you what to do. But you need knowledge to understand that too. The design can be faulty, you have to rectify that yourself. That is why it is not for you. Stop shouting. Your language is highly in appropriate. It is not formal or debatable. Bcs it is insulting. You do not have the skill to talk properly. And you say I am not 😡. Your words speak about that, Sir.
Sir Toshiba 5200 transistor के colector और emitor में 200 k का रेजिस्टेंस दिखा रहा है नए transitor में । अलग अलग lot के लेकर देख लिया। क्या यह transistor amplifire में लगाना उचित रहेगा या प्रॉब्लम करेगा।
Sir mai cd3161 ic based prehead kit mai head k jagah blootooth kit lagna chahta hu kyuki isake output mai bass quality bhut achi aati hai . Lekin awaz kat kat k aati hai.. Please is pr video upload kriye.
सर जि सांउड कोलेटि अच्छि सर्किट( प्रि ऐंम्प मोडिफाइड) और अछ्छे कंपोनेंट से आति है सबसे बढिया प्रोडक्ट युस करना सब के बस की बात नहि होति सब क्या सोचते हैं कि कम दाम पर केसे चिज को बनाया जाये और सेल कियाजाये
Sir is board ko mene bhi banaya tha ek bar Kai bar power transistors kharab hue is board me 100ohm ke resistance ko 150ohm me karne par kuch fark pada tha aur ye board accha nahi hai kyoki without load ke transistors heat hote rehte hai present se set karne par heat kam to ho jata hai par driver transistors ke +- volt equal nahi rehte diffrence bana rehta hai
A wala circuit Rod Elliot P3A amp circuit . And the led fed green colour ka hona chaiye .Tab jake achha bias set hoga.nehi toh bias kam or yada ho jaye ga.50mA bias is perfect for one pair.but for light heat sink bias kam rakna chaiye.😊
You should have studied the circuit in question before commenting on the design drawbacks, otherwise you sound like you aren't qualified enough to talk about this topic. I thought you were some kind of audio guru with such a huge following behind you, you can do better, why not do it right then
