ABSTRACT:
A vacuum tube circuit is capable of amplifying an input signal with use of a low source voltage. Ordinarily, the amount of electrons released from a cathode which is heated by a heater is small since a voltage supplied to the heater is low. In the vacuum tube circuit disclosed here, a positive voltage is supplied to a grid terminal, which more effectively attracts the emitted electrons, thereby increasing the amount of electrons arriving at the plate terminal passing through the grid. As a result, a grid current and a plate current flow in the vacuum tube circuit, which achieves an operation for amplifying an input signal from a signal source.
