YaqinAudio
Yaqin is one of the more prolific Chinese manufacturers of valve (tube) based audio equipment. They claim to have 'engage[sic] in power amplifier research and production more than 10 years' http://www.yaqin.cn/en/company.html.

Yaqin equipment is primarily designed for a 220Vac mains electricity supply voltage. In countries where up to 240Vac is normal, such as the UK, some caution should be observed.

Little reliable english language data is currently available. Often comical Engrish translations exist, for example see the nonsensical use of the terms ' gall stone' and 'gallbladder' in this sentence: 'First class-B gall stone is combined , grade is SRPP circuit before the gallbladder. The wide speed is fast frequently, the sound is nice.' http://www.yaqin.cn/en/products_hf.html

Notes
The name 'Yaqin' is probably derived from the Chinese musical instrument 'Yazheng' but may also relate to the Arabic work 'Yaqin' meaning certainty, or that which is certain. It is also notable that the logo contains the Greek letters 'Ψ' in place of the 'Y' and 'Θ' in place of 'Q'. This has led to many confusing alternative references on the web to both 'Yaoin' and 'Yaquin'.References
