Summer is over!<\/span><\/p>\n

What did you make by your hands?\u00a0<\/span><\/p>\n

Here is a project to change our mind and come back stronger<\/span><\/p>\n

\"\"<\/a><\/p>\n

Maybe you also learned amplifiers in school<\/span><\/p>\n

MX50 SE is only NPN\/PNP transistors and no coil<\/span><\/p>\n

\"\"<\/a><\/p>\n

This regulated power supply will do the job<\/span><\/p>\n

Power supplies, in any project, are as important as the other parts<\/span><\/p>\n

\"\"<\/a><\/p>\n

There’s also a mains filter, a rocker switch and a fuse holder\u00a0<\/span><\/p>\n

\"\"<\/a><\/p>\n

As usual resistors are soldered first<\/span><\/p>\n

\"\"<\/a><\/p>\n

Then it’s the turn of the transistors with the usual precautions<\/span><\/p>\n

\"\"<\/a><\/p>\n

Now you have to take care of the highest components<\/span><\/p>\n

\"\"<\/a><\/p>\n

Here is the method used to ensure that the power transistors are properly cooled<\/span><\/p>\n

\"\"<\/a><\/p>\n

It is mandatory to make a star ground
\nbe carrefull to the hot weld!<\/span><\/p>\n

\"\"<\/a><\/p>\n

It’s time for Ganesh to quality control the box!<\/span><\/p>\n

\"\"<\/a><\/p>\n

Final checks before closing the enclosure<\/span><\/p>\n

\"\"<\/a><\/p>\n

For next year there is a speaker protection and a motorized volume<\/span><\/p>\n
