Sir i have a request to you sir please make a video and tell how we can modify 3055 only NPN transistor Board with 5200 and some tips and tricks on it please And sir your skills are amazing

make that video drawing the schematic of this amplifier... of the driver board... very beautiful

👍

Mica sheets se accha hai ke ek thermal paste mai canvas duab kar single big piece use karna accha hai kyu ki short ka chance kam ho aur technical yhe best way hai kuy ki is ka result approx thermal pad kitna hota hai .jo mica sheet se bhi accha hai .mai apne har board mai yhe hi lgta ta hu

👍👍👍👌

Will be very thankful if you kindly if yu create tutorials on making PCB using software

Ek esa pre amp banaye jo bass tribal mid subwoofer our frecvansi 5 potetion lagake compact board banaye hame besbrise inatjar rahega

I am santosh Kumar bihar se sir aap jo bhi amplifier repair karte hain 1000watt. 500watt ya 3000watt a2z jankari दीजियेगा sir 3000watt module ka jankari bahut kam है sir प्लीज help me

ISI board mein 6 pair ka with relay speaker protection board Aata hai vah 2 Omms per work karta hai kya and power supply voltage kya rakhe sir g

sir single supply 0-12v subwoofer par video banaye na..

Maine ye board ke 2 channel banaye hain . Maine ek bar ek channel ke output me heating coil (4 ohm) lagaya tha to uasape 12 a tak ja raha tha to usaka aawaj dusare channel ke mukabale kam aa raha hain Biase voltage bi donoka aalag aalag dikha raha hain

Namaste sir class AB amplifier500w me ne bananya he cebnet gnd kese Kaur pf se ya darekt. Bataiye

Sir diapram bar bar jal jata hain, uskelien protection ka jugad ka video banayen

Well please,let them know about the difference in a.c and d.c voltage.. No one can save them if they r using ac. as the marked voltage

Uba 800 ke testing and ripeyrig volt ke bare me bhi btaye plz

Sir, 5200 aur 1943 transistor ka base per kitna voltage aana chahiye?

Sir good video. Sir ak class d ka amplifier banake video lao

Sir ek power supply capacitor or diode calculate kayse kore ek video banaye

Nice video sir...yea board + - 60 v DC se 8 ohm pe kitna watt deliver kar sakta hai

सर 2sa1494 ओर 2sc3858 के बारे में एक विटियो करेगा साब ? .. ये इथर मिलता है ? इसका कीमत लगबग कित्ना आता है .

Sir... 120w pa amplifier full circuit batao plz.

Sir aapka hand drile kon sa hain ..please bataye...

Sir d1047 transistor ko bd139 se draiv kar sakte hai kya🙏🙏

bhai ji plz. mv collection ke 3500 watt wala class d ka boards ki driver circuit ka video bana🙏🏻

Ap ek video iske baren v batao plz

Namaste sir Sir class d Jo circuit banaye the uska Bhi prectikal kijiye aur volt Kaha Kaha Kitna Hona chaiye plise bataiye thankyou sir

Sir rx3000 driver board par video banaye please

Namskar.. Sir Aise hi online pr 500/600 watt ke mono bord available hai.. 2mono bord add krke 1000/1200 watt ke booster amplifier bana sakte hai kya.......

Ji sir mene 2 500w ke board magayae the wo 8 ohm pe shi chalte h But 4 ohm pe chalane pe bahut jayada heat hote h Dono board 4 ohm support karte h fir bhi heat ho raha h Jo board aapne tumbnail me use kiya h wo board h mere pass Please koi solution dijiye

Sir , I have the same board , it's new and after testing I found that it is having crossover distortion ( on oscilloscope).what could be the problem ? I had bought 2 boards ,both have same problem . I see that the bias resistor is 10 ohms 1 w in the above case . But generally I find that 2.2 ohms1w is used .Could this be the reason ? Thank you for an answer in advance .

biasing transistor ki voltage 1 volt ker de toh sound ki clarity bar jaye gi toh kya uski base pe 4007 diode ko remove ker k 0.9v ki zener use ker saktey hai

Hi sir main chandan boro love you

Sir koi aisa curcit bnaye joheet sink par direct kas jai
