ABSTRACT:
A record reproducing system comprising a displacement detection type cartridge and a reproducing circuit for converting the output signal of the displacement detection type cartridge into audio signals. Either the displacement detection type cartridge or a pre-amplifier in the reproducing circuit is provided with a temperature sensitive resistive element so that temperature compensation with respect to the output-temperature characteristic of the displacement detection type cartridge may be effected at either the displacement detection type cartridge or the reproducing circuit.
