Default newbies tutorial help..

When i posted a message earlier i got this thought in my mind..

Often newbies like me have a lot of trouble with starting off with understanding the fundas of SS amp design.

why dont we start a thread where the more experienced members handhold the newbies till they walk on their own.


its easy to simulate and observe a design given in a textbook but what if someone wanted to build their own.

agreed
most authors give their explanations abt the function of components in their design.

But can we start a thread where a topology is given and u give directions on how to design ?

First do a search for the thing you are interested in, in this case a Marantz Xxxx, and see if anyone said anything before about it. Might want to search for the exact term, otherwise all things Marantz will spring up... Then put up a new post (top of the list for a given category, and be sure to click the box "I have searched" and type in what you want to ask about!

Trouble shooting is a different art then engineering/design.

You can actually troubleshoot many circuits without actually knowing that much about how they were designed, or the details of how any given stage actually works!

Krish, For text books, there are many but Horowitz and Hill: The Art of Electronics has the advantage of being writen in an easy to read style, which is very useful if you want to read about something without doing mathematical analysis in order to understand the idea.

The online sites will help too.

There are many discussions on here where the way that a given circuit works, however they generally assume that you already know something about things like how a transistor works and how it is biased for example... but you can pick up this sort of general information from books and online sites. Youtoobe also has some tutorials, fwiw.

These should keep you busy for awhile!

There are many things to learn before you become "seasoned". So - you start at the beginning and start with a simple project that will develop those skills and firm up the knowledge. A bit similar to taking a "lab" class in school. You get a bit of "hands on" experience and the reward of having built something. Then you advance to the next stage - and so on. It will take time - but all things worth while usually do. Take the time to enjoy the journey and the new friends you will meet! 10 or 20 years from now you will spend fond moments recalling your first amplifier build and enjoy sharing your knowledge and experience with a newcomer that is just starting out on their journey into this hobby.

Oh - BTW - you should be prepared to make some mistakes - we all do!!

That is why we wear eye protection devices (safety glasses). Get them - use them! Also follow two person rule - when working around electronic things that can injure or kill you have someone around that can turn the darn thing off before you start to singe the hair on the other parts of your body!!
