Important Safety Information
Zeng DeJun is a well-known name in the Chinese audio industry where his reputation as a
designer, teacher, entrepreneur and business man is legendary.He's the designer of China's
first Hi-Fi vacuum tube amplifier, a founding member of the nation's Hi-Fi vacuum tube
industry and designer of many lines of hi-end multimedia speakers and numerous Hi-Fi
products with cult followings in Asia. In 1994, Zeng founded the Shenzhen V.A.L.
Technology Co., Ltd. to finally pursue a lifetime goal of manufacturing a line of unique
Hi-Fi retro radios based on the classic wooden receivers of his youth that first kindled his
love of radio.
Some of Zeng's earliest memories as a child are of the beautiful wood radios in his home
that brought voice and music and sparked his curiosity towards science and technology.
He recalls that as a young child he asked how such a box could do such magical things but
received no clear answer. One day, when no others were around, he opened the back cover
of the radio but could not find the small people he had imagined were inside. All he saw
were the glowing bulbs (tubes) and lumps of iron (transformers). His parents couldn't
explain how the radio worked and told him that when he grew up and studied, he would be
able to understand.
Thus began Zeng's lifetime love and curiosity in radio and science. In school and led by
teachers and others, he began to assemble simple crystal radios and more sophisticated
versions. Growing up in a remote area, radio was both the fastest and most effective way
to learn of news and information from the outside world. Later, as a new recruit in the
Army, he found and repaired a faulty transistor radio for a superior who was so impressed
that he gave Zang the option of choosing the specialty for which he'd receive advanced
training. Zang chose the communications corp where he was quickly trained for radio
communications. Always curious and inventive, he found existing military radios heavy
and outdated so he set about designing and building lightweight versions that earned him
an Outstanding Innovation Award and a transfer to the army research institute. Later, he
was sent to Beijing University to study where he became a professor and a new phase of his
life began.
Over many years and many changes in his life, Zeng found radio programming and music
to be a close companion that gave him strength to pass difficult times and challenges.
Having spent many years in the audio industry, Zeng is familiar with high quality music
systems and CD players but prefers the fresh music selection and information found on
radio. He prefers to work in an office with a good table radio and, in part, this is one
reason why he dreamed of designing and manufacturing a quality radio set like the ones he
recalled from his youth. Having designed and built the first commercial Hi-Fi vacuum
tube amplifiers as well as the Hi-End brand of V.A.L. tube amplifiers, he had often
thought of designing high quality table radios, and saw this as an area no other companies
had pursued.
