I have a Yaqin mc 13s with gold lion tubes I don't currently use. I have had it for several years and have enjoyed it toughly. No headphone jack though.
My advice would be choose your speaker matching well. 8 ohm , high efficiency speakers will sound the best. In your price range, you will be underwhelmed with tubes + <4 ohm 84db speakers. I matched the Yaqin to a pair of ELAC Uni-Fi bookshelf's at first and it was meh. Built some DIY high efficiency speakers and it was magic.
