Power driver with autobias for PushPull of power triodes or pentodes

I offer the latest autobias power driver kit. Reliable power signal for triode and pentode PP drive with four power tubes.Indication of autobias, delay of anode current growth after switching on the amplifier. Automatic control of continuous perfect symmetry of PP degree currents.A revolutionary look and great sound!The driver and autobias is assembled. You will need to solder the connection wires to the amplifier according to the detailed diagrams that are included. 

Use: 

  Set includes:- Russian oil capacitors and other brand capacitors- quality metal film resistors- ceramic Gold Plated noval Tube Sockets- the necessary hardware to install the printed circuit to the amp chassis- Fully assembled auto bias module Note:The cathode current tubes are set only once for each as instructed in the wiring diagram..Trimmer on driver sets exact symmetry of inverse signals at points A and B.No additional settings. The parameters are shown in the diagram. Tubes are not included.
