The power supply is also constructed on a perfboard. For the power supply Thomas uses a 120VA torroidal transformer with dual 18V secondaries and generally followed the "snubberized" Gainclone power supply design by CarlosFM with 10,000 uF per rail.
For the enclosure Thomas used a Hammond satin black steel 12" x 8" x 3" chassis (Model 1441-24). The amplifier controls including a headphone output are on the front.
Thomas reports that the chipamp produces very good sound and that the small amp can hold it own against various high quality amplifiers that he has used. For complete project details, see the DIY TDA2050 Hi-Fi Chip Amplifier (chipamp) page.
These chipamps are simple to build, low-cost and when properly implemented can deliver very good fidelity. If you are looking for a project to try out, give one a try.
