 20 Watts per channel - pure Class A - 845 Single Ended Stereo Power Amplifier

 

Although the use of valves has decreased dramatically since the advent of the microchip

 it is still important to know its basic principles of operation.

Vacuum tubes are still in use today in high-power transmitters, audio amplifiers,

and in these and other applications demanding large dissipation of energy,

                                                                                   will continue to be used for a long time yet.
