This tiny Amplifier has more power and sounds better than many bigger one, I brought it used and as it was a keeper, I removed all 85 c, Taiwanese Jamicon regular capacitors and fully recapped it with high quality Japanese genuine Nichicon Audio Grade capacitors, as it was not for sale, profit was not an object and I used all top quality, 105 C capacitors, ordered from Digikey (Not from eBay or Amazon as some sellers sell fakes), 

The amplifier has dual, 130/230 voltage switch and can be used in the USA and also in other countries.
