- Notes
- With Resistor cord 210-240 Volts. Up to now we believe that model D-508 and D-508A is the same - just a shorter writing. NOrmally in the plan you find D-508 and on the plate D-508A. On the schematic (D-508) the model(s) show BC 540-177 Kc, Band 1 16.7 to 5.3 Mc and Band 2 5.5 to 1.9 Mc. Please add your remarks if you come accross of any differenciation. Since there still may be found differences we leave the new model D-508A and don't delete it as a doublette. See book references and other plans on model D508.
