  • Annotazioni

  • Some models with 6U5 tuning eye. 5 or 8 inch speaker. The Sentinel chassis 204-A have the same schematic but different cabinets. Assumptions for the suffixes: 204-A (not sure if this is only the chassis name, no cabinet, A probably for AC), 204-AT (T for table), 204-ACE-CB (C for console, E for magic eye, CB fro record player), 204-ACT (C = console, T = tall) and 204-AE (E for magic eye). Tuning is broadcast 540 to 1730 kHz, automatic volume control (AVC). 3.5 Watt power output. The same line exists as 206-A chassis with the same cabinets but the chassis provides additional short waves 5.7 to 18.3 MHz - see for instance 206-AT.
    * Models can have a different power transformer:  11272 (39) for 115 volts 50 cycles, 11273 (40) 115 volts 25 cycles, 11719 (41) 110 - 230 volts, 50 cycles or 11721 (42) for 220 volts, 50 cycles. Models -CB are "combinations" with phonograph. See 204ATE-CB, 204ACE-CB (and 198ACE-CB).
