A circuit device for a television receiver having a tuner device with a tuner memory operable to control the tuning of the receiver to stations selected by a user, in which there are further provided means for automatically adjusting the controls of the receiver whenever the station to which the receiver is tuned is changed, this means comprising one or a plurality of random access memories addressed by signals from the tuner memory which are characteristic of each individual station, the output signal from the RAM, (or the enabled RAM if there are a plurality of them) representing the contents thereof at the location addressed, is fed to a digital-to-analogue converter which produces an output voltage signal for adjusting the associated receiver control; changes to the content of the RAM can be made by means of an associated counter controlled to count up or down by a push button panel.
