Simple amplifier in the modem case


I decided to assemble a small-sized power amplifier.
The class D amplifier on the RAM8403 chip was taken as the basis. Output power 2 * 3 watts.

We will need:
- an amplifier based on the PAM8403 chip, a ready-made module from China is used;
- output connectors are taken from an old tape recorder;
- the case of an old modem;
- power switch, removed from the old computer PSU;
- power connector from an old printer.

Mark the back panel under all the connectors. We cut openings for the switch and power connector. We fasten the socket with marked holes.

We paint from a spray can. Dried and looks decent.

Device power, 5V adapter stuffing

We place all the blocks in the case and solder the wires. Connectors with glue on epoxy glue. The power adapter turned out to be with a USB connector in the case, excellent, useful. We bring USB sideways, it will serve to charge gadgets.

We collect everything. We solder.

We are testing. Everything works great.

Details of the assembly can be seen in the video.

Good idea, used to be called "Weekend Design."
Any glue of its kind is suitable for its purpose.

I always like glue on epoxy, epoxy is not static. And thermo-snot is a good thing and superglue with soda. A lot of things are glued and held super)
While the author applied normal material, not shithot melt.))
True, the description is kutsee, but from the video it follows that he put the boards on the epoxy, which is not good.
And what does epoxy glue have to do with it?
It seems not an article about him?
It is very interesting, just at home there is an old Dir300, you need to do it. Thanks for the little idea)
Respect for the use of epoxy glue to the author.
