The key of signal to noise ratio；So, one " big energy, high speed, unrippled, the power supply of zero internal resistance " be that we are pursued
Dreamboat.
The technical barrier that audifier power supply is faced is:
1) during electron tube work, under conditions of filament to be fully warmed-up and to require to be operated in low-voltage, big electric current；And remove filament
Outward, in the state of electron tube operates mainly in high voltage small area analysis, this difficulty for voltage stabilizing is powered strengthens.

High s/n ratio is totally unfavorable.And under the current current situation of power supply of China, it is ensured that the output of power transformer always maintains
Also there is certain difficulty at 6.3V.It is known that filament power supply instability will highly impact the life-span of electron tube.
3) it no matter is directly-heated type or heater-type tube, be all by thermionic emission work.In order to strengthen emission of cathode
The ability of electronics, typically can be coated with the oxide of thin layer at cathode surface, and this coating can not be accomplished very uniform, thick
More greatly, heating is also big for ground resistance per square；If voltage is too low, the power of heating does not reaches setting, and negative electrode just cannot be normally
At a temperature of work, it is easy to cause hot-spot to be damaged.When the electric current of negative electrode is not enough, these have negative temperature system
The resistance of the oxide layer of number will be bigger.If screen positive pressure is often constant, grid inputs a big signal, the place of result thick coating
Owing to resistance is relatively big, when screen stream flows through, heating is bigger, thus " is siphoned away " more electronics, the need increasing with satisfied screen stream by anode
Want, evaporate so be easily caused negative electrode local excessive on the contrary when filament voltage is too low and be damaged.If instead heating voltage
Too high, the evaporation of whole cathode surface layer oxide also can be accelerated, and can shorten again the life-span of electron tube.
