A note to all those reading this. Not so long ago KZfaq wasn't there. We had to rely mostly on our lecturer and ourselves. Even books were a luxury. So take advantage of this and make the most of it. A special thank to Mr Haseeb for sparing some of his time.

Excellent explanation. Much clearer than others I have watched. I restore vintage computers, and have a handful of dead PSU's. This makes it much clearer what I'm looking for instead of randomly probing around the board. Incidentally, I have an old Olivetti PC6300 PSU that has a Gammatron T366 transformer(?) and an MPX-A-100 relay that perhaps serves in place of the optocoupler? It does seem to fit your model, because it and the Gammatron appear to isolate the input from the output. I'm just now making my way onto the output side where I suspect the issue lies. Again, excellent explanation friend. Thanks for KZfaq'ing!

He has a wonderful voice and I always understand him perfectly. And it’s really soothing to listen to him. He speaks perfectly But I still appreciate whoever did the English subtitles because sometimes I also like to read along… Even when listening to American accents… It helps my brain if I can read it also. So big props and thank you to whoever did the subtitles and took the time.

I have few ones in the junk box it will be a good starting point for me (I will use then with an isolation transformer and make some experience has described here.) this is definitively the best SMPS training on KZfaq.

Haseeb ! Thanks So much ! for all your great SMPS videos....I am currently attempting to repair two SMNPs and after watching your videos, I actually have a pretty good understanding of how to trouble shoot SMPS issues, rather than just changing out every electrolytic capacitor and HOPING that fixed the problem.... I was up half the night last night watching your videos, and will probably need to re-watch them a few times so I really grasp everything you show us..... Can't we just come up with a way to direct download the knowledge from your brain to ours ! :-) EXCELLENT STUFF ! Thanks Again ! Rick

So...I know it takes time to make these video's. And the individuals who take this time, which is a un-renewable portion of life, are either wanting to share their knowledge for the hope of bettering this society or are doing it for money...regardless if the information is correct or not. Or maybe they just want to show off. After years of looking at these circuit boards and trying to make sense of the process, this video breaks the SMPS down into sections and shows what is happening in each. Another chunk of knowledge added to my library. Thank you sir. I typically exit videos when the commentator has a heavy accent. It is difficult for me to follow. Has something to do with the number of vowels and stress points and... I have researched it some and it gets complicated. I here you relaying much information and in making it simpler for us commoners to follow you seem to speed up your explanation. I may be wrong. What I am saying/suggesting/asking is...to take more breaths so I, and possibly others, have that time, (precious resource) to comprehend more fully. Doing my best to comment without insulting. Much information out there...hard for me to understand and follow along. Thanks again...sincerely!
