#LA4440 

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।

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 🎶🎵😄

Pehle me ye 4440 dual ic ( delhi Made usb digital player 750 rs ) ko good Manta tha , lekin ye video dekhne ke baad sab kuch naya leke assemble karvaya , yakin mano aavaj pehle se kahi guna achhchhi ho gayi hai , thank you sir 🙏🏽

Sir bahut useful video banaya hai aapne I like this video 👌👌👌👌✌

जी बात तो सही है....... सबसे पहले तो आपको "नमस्कार" मेरा परिचय (दीप त्रिपाठी = मण्डे स्क्वायर) से, आपका समझाना, ना चाहते हुए भी कार्य कुशलता के लिए प्रेरित करता..है.. .. आपकी हर एक वीडियो का धन्यवाद....... 🙏

sir mere pass ek 4392 stk audio board hain 16-0 v ka.kya hum usse 12-0 v par chala sakte hain?

Thanks for theory

Thanks sir g

Best👌video 4440 ic

Main 10 Sal se kam kar raha hun per mujhe bhi nahin Pata Jo aapane bataya🤗🙏🏻

sir agar 1000uf ka cap 11 pin ke pas lagana hai to rectifier vala capacitor nikal de? ja rhene de? kiyunki agar 11 pin pe 1000uf ka cap lagayenge to vo cap rectifier capacitor ke sath parallel me aa jayega jiss se unski capacitance change hogi to iss se farak padega?

Nice video Sirji ...bahut bahut abhari hoon...4440 ic board keise 2.1 home theater me use karenge...uska update video banaye plz

Yeh video mera kaam ayega kyuki maine f.kart se salcon ke 4440 board mangaya

Bhai sahab apne LA 4508 ic ke bare me nhi bataya... Pls bataye udki audio quality bhi dam dat hai.. pls batao

Good

Nice

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

Thanks sir
