So the little Lepai amp stopped working this week (original post here), after a bit of investigation which I originally assumed the amp has failed, but by swapping over the PSU for another one it appeared that the PSU had given up the ghost and not the amp.
What ensued was a quiet couple of days of quiet while waiting for the new PSU to arrive.I choose to upgrade the PSU to a 12v 5amp rather than 12v 2amp that I was previously using. The amp can work with both and will just draw the power it requires, some have concluded an improvement in sound quality when using a 5amp supply. The old was was a samsung one left over from an external hard drive and was already a couple of years old.
Anyhow hopefully this will last longer than 11 months!
I had been looking for an amplifier for the workshop for a while and read about these small and cheap amplifiers on the DIYAudio forum [link to diy audio posts]. The posts suggested that although cheaply made the amps sound great and are very easy to mod. So order placed and £19.99 later it arrived. My new version can badged as Lvpin, the new name for Lepai (apparently meaning “dependable product” in Mandarin”). I ordered one without a PSU, I happened to have an external hard drive PSU offering 12v DC 2 Amps output so I hooked that up first to check how this budget amp would fare.
