Neat build, but I don't like the use of an automotive in line fuse holder for 240v mains.

At last finished my first build and itching for my next any suggestions?
Maybe a MX50 AB and build the board.

Thank you to all that helped me on my 1st build.
Sexy amp ) well done
I suggest you to get the HanZao TPA3255 or the Hypex NC252MP module, you won't be disappointed for a next projet )

Default ICEpower 500A

Nothing particularly special about this one (and not much DIY ), but it sounds nice. Will have to tidy up the wiring, especially the Arduino/relay portion. Enclosure and power supplies are from audiophonics, the ICEpower modules are from a user here on diyAudio.

Front (the white thing on top is this).

The RCA connectors are awesome since they have the nuts on the outside - you can remove them without desoldering any wires (or solder the wiring and then mount them). The speaker binding posts not so much. I'm unable to solder anything on them with my soldering iron.

Insides:

Funny thing about the enclosure: it's mediocre at best, but the lettering (silkscreen?) is the most durable that I ever seen. I was able to get it off the front panel with a razor blade and copious amounts of solvent. The back is a different matter. The solvent dissolves the black paint but not the blue lettering . And it stinks. Like literally, even after a month on the shelf, it still absolutely reeks of something.
