Very informative video. Your diagrams are very neat and easy to understand. You covered all aspects of testing board in details and explained in a lucid language. Your all videos are very useful to all of us. Thank you.
Sir main apke amplifier ke har video dekhat hu bahut hi Imfomative hote hain Aaj ka aapka testing board video bahut accha hain, uska components fitting ka sample board video bannaie
Isme fuse protection missing hai. Wo hota toh aur maza aata. Variable supply ka ek module incorporate karne se aur behtar hota aur computer ke power supply se ye 5v , 3v, 12v , aaram se mil jayega wo bhi 100 rupaye me short circuit protection ke sath. Heating coil ko kisi ceramic powder se coat karna aur behtar hoga , Isme inverter check karne ke lie DC battery ka option hota toh aur maza aata . Kul mila ke thik hi hai bus heater coil ko bahar hi rakhna hai enclosure se.
Sar namaste main Babulal ji Mumbai se jo bhi Sar aap batate hain aap apne Instagram per ek hi FIR aapane RU-vid per bahut Achcha batate Sar Bhagwan aapki Umra Char Guna aur badhaen aur aap Aksar khush rahe aur aap aise hi ham log ko sikhate Rahen aapke Aashirwad se ham log ke bhi ghar aur Parivar khushhal Rahega aur aapko bahut bahut dhanyvad deta hun aur Sada aapka Ham aabhari Rahenge jitne Hamare RU-vid mein dekhte hain
Sir, the heating coil wattage is not mentioned here. Please give details of coil which is available in the market and also for 2000 W. Mention the 20V zener wattage.
Sir amplifier board me high and low bass kasse kar sakte he without any bass treble board only using pf in board. Or sir professional amplifier me bass kase jada hotiye or voice kam hotihe, high frequency jada atihe, kase sir ???
Sir ji ek bahut hi zaruri subject pe aapne video nahi banaya hai. Trsfrmr and amp board fuse protection. 100 to 500watt board ke liye ek protection video bana dijiye. I think sabko iski jarurat hai. 230 volt ac to trsfrmr and trsfrmr to amp board. Thx
Agar supply voltage plus mines 100 volt hai To Ek payer trangister 1 empier current maximum leta hai aapke 15 pair Hai To aap 10 se Lekar 12 ampere ke bich mein Transformer Laga sakte hain
