That explains it.

The SMPS is bought. Focus was on the design of the class D amp.
More details here:
SystemD_2kW, any interest for an open design?

Hi guys,

I used to drive my previous speakers with my TA2020, a seroulsy modded Helder MkIII,
a sweet tiny amp,
and now I'm quite happy to have finished my TK2050 after many years in a drawer... It's now holding old JBL 4311 quite nicely.
Internal sub-casing (with metal sheets) and cooling (silicon pad between heatsink and top case) are the last things to be done.
DIY is fun! And it does sound good!

Default First DIY Amp

After a long time trawling this forum, I finally put together a class D diy power amp built from two LJM L15d PRO modules, and powered by a connexelectronics 500W SMPS. Was pleasantly pleases by the sound quality of this build. Notice PSU is housed in a separate housing until I get a proper enclosure. Being a first built I made do with what was available to see if it merits further expense. I surely will be getting a proper amp enclosure. Any advice especially regarding wiring is welcome.
