কৃষ্ণেন্দু বাবু আপনার যতগুলো ভিডিও দেখেছি, তার মধ্যে এটা আমার সবথেকে বেশি ভালো লেগেছে, কেননা আপনি ভিডিওটির মধ্যে এতটাই বেশি পুঙ্খানুপুঙ্খভাবে বুঝিয়েছেন যে আপনার প্রশংসা না করে পারা যায় না,
হ্যাঁ আপনার হিন্দি টা আরেকটু আপডেট করার প্রয়োজন আছে এতে কোন সন্দেহ নেই, তবে এটা এমন কিছু ব্যাপার না হয়ে যাবে.. চালিয়ে যান সঙ্গে আছি

Dear
earler i fix 2ty pnp smd txr in positive and j3y npn in negative source that time getting
4 v dc out put .
when i seen your transistor vedeo smps then
i reverse both smd trsnsitor but out put not showing any voltage . you suggested for str
module modification can str module will fix in
12v 5 amps smps power supply. or which
number npn and pnp transistor fix in this power supply 12v 5amps.. you earlier suggested 9401 and 8550 transistor . can we fix this yransistor in our 12v 5 amps smps supply. pls reply sir i only dependeding on your
suggestion . pls suggest me. i highly request you .

Nice video Bhai, pr mujhe ye beech wala transistor Samajh Mein Nahin Aaya feedback ke hisab se MOSFET ki switching kaise karwata hai
Thank you so much❤

[@easyknowledge3342]

In another video I will try to discuss its transistors in detail

[@satyanarayansahmm.9845]

Dear
excillent vedeo seen .
our two smps 12v 5amp same circiuit
faulty due to both npn and pnp transistor faulty and number also not visible.
can you explain dear both npn and pnp transistor number so can solve our problem.
with thanks and regards

[@easyknowledge3342]

9014 in place of npn transistor and 8550 in place of pnp transistor

Auxillary mai jo diode se ground hai agar usko gate mai laga ke ground kar dey to kuch garbar hoga kiya ..q ke ek circuit mai aisa dekha mujhe

Dear
what is 10/50 in citcuit written near oxilary winding. in my circuit 12v 5amps written 10/2. so want to know what is 10/50
pls guide me dear. i still stuck in my
circuit .
with thanks and regards

Sir badhiya power supply kaun sa Hota Hai 12 volt 2 ampere

[@easyknowledge3342]

Any 12 volt 2 amp SMPS you can modify will be fine

Hello sir is circuit me STR 888 / 5LO380R / Module install kar sakty he pmw volt kesy bany thinks mere paas 12 volt same supply he sab shot he modul install str 888/ 5LO380R thinks

Lenovo laptop adapter sm transformer damaged how to find new one

[@satyanarayansahmm.9845]

dear
thanks pls guide me sir both transistor are
npn connected or one npn and another pnp
connected.
with thanks

[@easyknowledge3342]

You can replace n-p-n transistor with 9014 and pnp transistor with 8550.

[@satyanarayansahmm.9845]

Dear
many many thanks for reply as per you
now will search both number in smd transistor number package then will fix
with thanks and regards

[@easyknowledge3342]

If you don't have smd transistor then channel 5l0380 there is a str modification video you can install it will be very nice

Sir, Transistors & Mosfet Number ?

[@sngaur2010]

Nice explaination, but you did not explain about the function of PNP transistor properly. Please explain. Thanks

[@droopings]

yes. pls explain
