Homemade amplifiers according to the Master Kit ON TDA2050 scheme and a homemade power supply. DIY. EVERYTHING IS FURNISHED IN THE HOUSING FROM POWER SUPPLIES.
Hello! As usual, the video says it all. Master Kit kit for soldering an amplifier on the TDA 2050. I bought it, really liked it, I decided to make a couple of such amplifiers, I bought separately radio components from the list and soldered the stereo amplifier. Everything is powered by a home-made power supply, which is based on a transformer from an u-101 radio amplifier. And he also decided to arrange everything in old unnecessary cases from computer power supplies.
A ready-made or soldered constructor from a master kit costs a few hundred, and if you take the radio parts with a list, well, about 100 rubles everything works out, a maximum of 150. What did you like about the TDA2050 kit, it has a wide supply voltage range, i.e. it will not burn from 14 volts, it can be pumped at 30+ volts, and at 12 volts it starts up into a light one. In general, I think that this amplifier is not bad enough, and universal, so I decided to repeat it several times. In fact, somewhere else a couple of such boards should be installed, but I don’t remember where they were doing.
Here in the photos a whole set is presented craftsThis is a monophonic amplifier for a subwoofer, a stereo amplifier for Pioneer speakers, and a power supply unit based on a transformer from an old Soviet burned-out radio amplifier u-101. And by the way about the subwoofer, just the previous one homemade presented on this site I have about the highlighting of the subwoofer, which is at the end of this video. To whom it is interesting to look.
In the photographs, the other power supply also flashes in places, this is the second option, there the secondary was rewound from the production transformer and made for several voltages, I wanted to use it first to power the same amplifiers, but then I returned to the version of the power supply based on the transformer from radio engineering. And as usual, everything is described in more detail in the video, plus verification tests.
