ABSTRACT:
A current transfer amplifier includes a voltage signal source for supplying a voltage signal to be amplified, a voltage/current converter for converting the voltage signal from the voltage signal source into a current signal proportional to the voltage signal, a tone control circuit of a current amplification type supplied with the current signal, a non-linear switching element interposed between the output of the voltage/current converter and the input of the tone control circuit to transmit the current signal therethrough, a variable resistor for receiving the current signal to produce a voltage signal proportional to the current signal.
