djank ... english please

maksim, super nice
Is it your own construction or fabricated modules?
Is it a new case or from an older amp. It looks really cool.

Though I think the heat transfer from modules to the heat sinks will not be really efficient, but then again, propably not needed either

Best regards Baldin

P/S Thank you for your comment. User djank asked about a second channel amplifier. I told him that it will install later.

This is the reference design for the IR2092 controller chip, if you want to try building from scratch. ljm_ljm here has used it as a basis for his L15D and L20D class D modules, which are so cheap that it hardly makes it worthwhile to design your own. Check out the other threads about them in Class D forum

Default Poler's amp

The case work is beautiful.

How were what appear to be vents cut?

What is the front of the cabinet made of?

Is the power light an add-on or is it from the power supply?

Thank you for the comments gentlemen Davet the vents were cut with laser, the front of the cabinet is made of white acrylic which was also cut with laser for the light hole and the switch button; the light is an add-on. I am finishing a new amp I am building for a friend i'll post the pictures soon. Happy new year DIYers!!
