Summer is over!
What did you make by your hands?
Here is a project to change our mind and come back stronger
Maybe you also learned amplifiers in school
MX50 SE is only NPN/PNP transistors and no coil
This regulated power supply will do the job
Power supplies, in any project, are as important as the other parts
There’s also a mains filter, a rocker switch and a fuse holder
As usual resistors are soldered first
Then it’s the turn of the transistors with the usual precautions
Now you have to take care of the highest components
Here is the method used to ensure that the power transistors are properly cooled
It is mandatory to make a star ground
be carrefull to the hot weld!
It’s time for Ganesh to quality control the box!
Final checks before closing the enclosure
For next year there is a speaker protection and a motorized volume
