Thought I'd start posting a worklog on a side project I've been fairly busy with. It started out in life as a Lepai LP2020A+ stereo amplifier (pictured below), but now the amplifier has its guts spilling off to the sides. It needs a case.
I've added a relatively large hand-wound air core inductor to replace the relatively small stock air core that couldn't handle the additional amperage from the larger 12V5A aftermarket power supply. A 4700uF Nichicon Al-e capacitor in parallel with a small tantalum 1uF capacitor replaced the fairly pitiful stock 2200uF Al-e power filter/bulk capacitor. Eventually, I'm going to move on to replacing the no-name "Low-ESR" stock capacitors in the tone controls and on the input side with Elna SILMIC IIs to smooth out any mid-range grain.
Glad to be back in the creative mood.
