  • Notes

  • The UE65 Emerald is an AC/DC operated, 6-tube, BC and SW band receiver.  Uses ballast tube L42C.  This is the E version that has magic eye tuning.

    The updated U & UE model schematic (Rider's Vol. 9, p. 9-2) is very similar to the earlier U model schematic (Rider's Vol. 8, p. 8-16).  Both versions use the same parts, however the eye tube is wired differently in the updated models. 

    Also note that the model names were clarified: the updated U models now have no magic eye, and the UE models have magic eye; much less confusing than the prior U models where the with and without magic eye models were all U models.

    Also uses a Bias Cell.

    Note that there are multiple models of the Emerald; some models may have different brands as noted:
