Vacuum tubes,thermionic valves,made it possible for technicians and circuit designers to manipulate the feeble electric signals decades ago.The first vacuum tubes were thermionic diodes which were used exclusively as rectifiers.This type of electronic device had only two eletrodes-the anode and the cathode.With the introduction of a third electrode,the gird,as a controlling device the triode vacuum tube was born.Tetrodes and pentodes were also built later on.
Wih this discovery,the world of electronics is suddenly here.It changed the way we do things,in fact our life is no longer the same any more!
Today,the vacuum tubes is just a thing in the memories of us old timers,many of the young engineers of today may have never hard of them before.Yet vacuum tubes are still in use in large broadcasting transmitters and in the homes of the audio hifi fanatics.The output of the vacuum tubes audio equiment have much higher fidelity than their solid state counter parts.Hence they remain the favorites of the hifi enthusiasts.
I will share with vacuum tubes(valves) lovers what little I know on this subject in this blog.
Vacuum tubes,sometimes referred to as thermionic valves,are the first generation of electronic devices.I will share with those who are interested in my experience and knowledge on this subject.
