Decent quality components and good caps rated at 105 deg C, and sound is good. This amp runs well on; battery's, power supply linear and switching, has tried voltages from 8 to 15v. The soldering spots at the bottom is small and a bit difficult, but had no problem with 0.56 mm solder.

Very capable compact amp at a very low price. I power the amp with a 12 volt DC adapter and I use the headphone jack on my laptop to the input of the amp and the output is hooked to a pair of bookshelf speakers. I get lots of sound and use the computers EQ to adjust bass and treble, it's a great little set-up. One note would be to use heat transfer paste on the two outputs to allow for better thermal transfer to the heat sinks.
