Wi Wi Trading Co. Ltd. was established in year 1970. Trading of tubes/valves was one of the minor sectors of the Company's business in '70s. The business expanded in early '80s, with more business locally and overseas. In 1980, the Company moved to its own building, which contains six storeys in the Central of Hong Kong Island. 
Mr. Tang realized that the irreplaceable richness of the sound from quality electron tubes would be in high demand by audiophiles. Therefore, he bought as many quality tubes/valves (most of them are discontinued items) as he could find from the markets, auctions and friends everywhere. 
In 1992, the Company bought another 2000 sq. feet warehouse, close to the office building to store all the tubes/valves. At present, Wi Wi keeps over 500,000 pieces of tubes/valves. It is one of the biggest electron tubes dealers in Hong Kong and Asia. It is also the distributor and sole agent for the USA Amperex, Bugle Boy and Cetron in Hong Kong, Macau and China. 
To ensure fast and efficient service, a computerized stock control system is used to keep tracking of all the rare and obsolete tubes/valves. All tubes/valves for wholesales and retail had been well tested and carry a guarantee.
