Amplifier basics

In the layout of an amplifier made by someone else, I am very concerned about the placement of transformers, power switches, neon lamps, and electrolytic block capacitors.

You can tell at a glance whether the designer is from an electrical school or has studied electrical engineering.

Now, let me tell you the main points.
When facing the amplifier, the power transformer and power switches should be on the right side.
Do you know why?
This is because the right hand has traditionally been used to turn on and off the power.
Basically, you do not turn the power switch on or off with your left hand, which is the side where your heart is located.

And when it's necessary to turn off the power switch in an emergency, such as smoke, it's also because it's my right hand to turn it off quickly and instantly.

The lifespan of electrolytic capacitors is greatly affected by heat. .
If you look for the data disclosed by the manufacturer, it will be clear, but depending on the low temperature, it can be used for thousands of hours, but if it is near a high temperature, it will be NG in several hundred hours.
Therefore, electrolytic capacitors should never be placed near vacuum tubes.
The heat will scorch it and shorten its lifespan. This may cause a malfunction.

Then, lay a signal from the left side and direct it to the power source.
You can understand a designer's ability just by knowing these points.

Of course, it's a fun audio hobby that comes with a variety of designs.
Arrangement is also important. It's boring if everyone has the same design.
An excellent industrial designer is someone who can incorporate all of these elements into a superior amplifier design.
Mr. Giugiaro, who was also active in cars and cameras, is a genius industrial designer.

In the world of audio, I have yet to come across a design that makes me fall in love with it.

If I were to pick something that I didn't like, I'd say the designs from manufacturers like Studer and Luvox are the best. For now,,.

However, in terms of vacuum tubes, the proportions of Toshiba's 5U4G and 5R4G are good. Like a guitar, it reminds me of a woman's body.
NEC's 211 is also cool, though.
