  • Notes

  • The Bush 'Teleflic' is a mechanical station-logging device with a rotary optical readout, driven from the tuning mechanism. Initially bearing just numbers, post-WW2 and commencing with model EBS4 it was modified to include a ring of letters which advanced one letter at a time after a full sweep of the numbers occurred to improve resetting accuracy. The 'Teleflic'  was intended to make it easier to retune to specific stations. It has no electronics other than a back light and it is not a "bandspread" mechanism, nor does it have any effect on selectivity. It is on at least the SW45, BA53, BA53 Export, EBS4, BA63 and PB53 models.
