#LA4440

Apply these modifications for blasting sound from LA4440 Amplifier Circuit. I have suggested these modifications to increase the performance of 4440. Method for heat and noise management is also suggested. Please watch the entire video for complete knowledge. IC 4440 से धमाकेदार आवाज लेने के लिए क्या करना है ? अगर आप इन तरीको का इस्तेमाल करेंगे तो जरूर इस IC को बिना ख़राब किये अच्छी और धमाकेदार आवाज ले पाएंगे.

[@Pritesh235]

सर जी में आप के वो वीडियो भी देख लेता हूं ,जिनका मुझे कोई काम नहीं है , सिर्फ आप की आवाज़ सुनने के लिए , आप का समझने को तरीका बेस्ट है।

[@mithileshgmishra6124]

आपने बहुत ही उपयोगी और अच्छी जानकारी दी है उसके लिए आपको बहुत साधुवाद ।। आपकी 4440 पर एक वीडियो देखी थी जो बहुत जानकरी युक्त थी आपकी एम्पलीफायर इंजिनीरिंग का ज्ञान बहुत विस्तृत है मेरा आपसे निवेदन है एक ओरिजिनल sanyo (जापान) की ic और कंपनी द्वारा दी गयी डेटाशीट के हिसाब से कंपोनेंट लगाकर ( एक हैवी हीट सिंक) के साथ बनाएं जैसा कि आपको भी पता है LA 4440 भारत राष्ट्रीय IC है भारत के 80% घरेलू एम्प्लीफायर में यही IC होती है 🎶🎵😄

Sir 6 amp par kuch hoga to nahi 12 volt 6 amp last

[@jagdishnayaklathi6210]

Good idea bhai

[@arismazimmer9275]

What I did first,.. I made a separate power supply box for 4440 amplifier. I removed the Transformer (12v 5A) from the main cabinet. This removed all noise, what I used to get previously when increasing volume. After separation of the transformer, humming, noise everything has gone. From the seperate power supply I carried 12V AC into the main cabinet (this reduces loss) and there a separate board I made for DC conversion and filtering. Power supply wires are 0.75 mm wires.

[@WhatIThink]

Good decision..Power supply is the main culprit here.

[@IAMONESHOT]

Sir ye duplicates 4440 ic ko 5 amp supply dena sahi hai kya, 5 amp duplicate ic jhel paye ga kya, iss ke pran tho nahi nikal jaayenge? 😁

[@donbhai1843]

Nice video

[@amitghosh6966]

Mere paas monty company ka single Ic 4440 stereo board hai aur usme maine kuch modifications kia jaise ki inputs me resistor ki jagah 4.7 uF capacitors lagaya jisse Dc na jaye ic me. Uske baad uske dono negative feedback pins 1 & 7 mein capacitors ke sath 100 ohms resistors lagaya series me jisse uska gain kuch kam ho kyuki uska gain 51.5 db hai aur isse noise jada hota hai aur sound fat ta hai full volume me aur resistors se gain 41.5 db ho jata hai. Isse thoda improvement hua. Aur finally iss board me Cd4440 Ic hota hai jo Chinese hota hai aur bad quality hota hai kyuki original Ic ab bandh ho gya hai par recently kisi Indian company ne firse ye Ic launch kia hai Sanyo La4440 (India) naam se jo ki licensed bataya gaya hai toh ye Ic maine change kia toh sound quality aur improve hua halaki Tda2030A, 7265 jitna quality nahi hai par Chinese Ic se kuch better sound hai. Aur jo aluminium plate iss board mein Ic se laga hota hai usko hi Maine heatsink compound ke sath metal cabinet me lagaya hai aur heat dissipation thik ho raha hai

Great

Is pr cpu me jo prossr k uper wali heat sink lga skte h kya fan k sath Fan ka alg transformer lgana pdega kya

[@WhatIThink]

Yes. Fan ki supply alag rakhna nahi to humming aa sakti hai. Ek bar try kar lo, agar humming nahi aati hai to ek hi transformer use kar sakte ho.

[@pradeepbisht1441]

Thanks for this informative video. I just want to ask sometime shield wire on volume also catch noise sound. I had faced this issue. But when I replaced with ribbon wire. The noise immediately reduced. I really don't know what was the reason.

[@WhatIThink]

If shield is used for signal and core is used for ground then there will be noise.

Nahi....Doosra board use kijiye...Clear sound ke liye kam se kam 100 watt ka board hona chaahiye aur speaker bhi acchi quality ka lijiye. Use tweeter also.
