Restoring a Pioneer SA 5300 amplifier

I bought this amplifier in or around 1977. Lately, I used the SA 5300 in the shed/workplace for music, where it was starting to rust. So I decided to try and restore it to its former glory.

After removing the cover, the circuit board proved to be easily accessible on both sides.

The circuit board with the original parts.

As you can see on these two pictures, many capacitors have leaked. So the first step is to remove all electrolytic capacitors. Note that C63 (just above the biggest capacitor) is missing, it is actually on the other side. Also note that C66, which, according to the schematic, should be 220 uF, actually was 330uF.

Old capacitors

These are the old capacitors. Two of the smaller blue ones have a resistor connected to it. These resistors are ok and will be put back. I have ordered new 85 degrees capacitors.

I replaced diode D3 (1S2473) with a 1N4148, and diodes D5 through D8 (SIB01-02) with four times a UF 4003. And of course all electrolytic capacitors. And the power light. After I replaced the electrolytic capacitors, the 5 diodes and the 4 fuses, and also the broken power light with a yellow led plus diode and resistor, as you can see bottom left, this was the result:

The underside

Notice the capacitor. On the other side, C63 is missing and moved to the underside, the minus connected normally, the plus connected to the minus of C68.

After cleaning all switches and trim-pots, the amplifier was connected to speakers and tapedeck for testing, resulting in a top score. Great sound, no humming or hissing or creaking when turning knobs. So, I deemed replacing transistors as unnecessary. Replacing the cleaned front and spray painted cover resulted in:

How to win friends and influence people.

How to win friends and influence peopleThis grandfather of all people-skills books was first published in 1937. It was an overnight hit, eventually selling 15 million copies. How to Win Friends and Influence People is just as useful today as it was when it was first published, because Dale Carnegie had an understanding of human nature that will never be outdated. Financial success, Carnegie believed, is due 15 percent to professional knowledge and 85 percent to “the ability to express ideas, to assume leadership, and to arouse enthusiasm among people.” He teaches these skills through underlying principles of dealing with people so that they feel important and appreciated. He also emphasizes fundamental techniques for handling people without making them feel manipulated. Carnegie says you can make someone want to do what you want them to by seeing the situation from the other person’s point of view and “arousing in the other person an eager want.” You learn how to make people like you, win people over to your way of thinking, and change people without causing offense or arousing resentment. For instance, “let the other person feel that the idea is his or hers,” and “talk about your own mistakes before criticizing the other person.” Carnegie illustrates his points with anecdotes of historical figures, leaders of the business world, and everyday folks.

Think And Grow Rich

Product Description
The bestselling success book of all time is updated and revised with contemporary ideas and examples.
Think and grow rich
Think and Grow Rich has been called the “Granddaddy of All Motivational Literature.” It was the first book to boldly ask, “What makes a winner?” The man who asked and listened for the answer, Napoleon Hill, is now counted in the top ranks of the world’s winners himself.

The most famous of all teachers of success spent “a fortune and the better part of a lifetime of effort” to produce the “Law of Success” philosophy that forms the basis of his books and that is so powerfully summarized in this one.

In the original Think and Grow Rich, published in 1937, Hill draws on stories of Andrew Carnegie, Thomas Edison, Henry Ford, and other millionaires of his generation to illustrate his principles. In the updated version, Arthur R. Pell, Ph.D., a nationally known author, lecturer, and consultant in human resources management and an expert in applying Hill’s thought, deftly interweaves anecdotes of how contemporary millionaires and billionaires, such as Bill Gates, Mary Kay Ash, Dave Thomas, and Sir John Templeton, achieved their wealth. Outmoded or arcane terminology and examples are faithfully refreshed to preclude any stumbling blocks to a new generation of readers.

About the Author
Napoleon Hill (1883-1970) enjoyed a long and successful career as a lecturer, an author, and a consultant to business leaders. Think and Grow Rich is the all-time bestseller in its field, having sold 15 million copies worldwide, and setting the standard for today’s motivational thinking.

As a Man Thinketh

by James Allen

This review is by John Chancellor.

This book is without equal when it comes to giving guidance on how to shape your life. The basic idea is not new. It is contained in Proverbs 23:7, “As a man thinketh in his heart, so is he.”
As a man thinketh
However the Bible verse is so short that many people miss the depth of wisdom contained in those few words. James Allen explores and guides you through the thought process. By reading this book, you will come to understand that “Man is the maker of his character, the molder of his life, and the builder of his destiny.”

“Men are anxious to improve their circumstances, but are unwilling to improve themselves;” As soon as you understand and accept the concept that unless and until you change, nothing in your world will change, then you are on your way to positive change in your life.

The book is very short, but word for word is one of the most valuable books of our time. It should be read often, at least once a month, until the words are imprinted on your subconscious mind.

This book makes a great gift. One that will continue to give.
