I have both Yaqin and Melody low-end tube amps that are nice and are made in China, I think the Melody stuff is a little better made and sounds better based on my amps.
Other Chinese brands you might also look at Dared, Ming Da, Doge, Yarland, Jolida, Cayin, Music Angel, and Xindak. I haven't heard these amps, but have heard of them.
As others have said, be sure that it is wired for whatever voltage you need.
