Notes
The model 71 series had many variations.

The single speaker versions use a code 121 chassis, and the dual speaker 71D uses a code 221 chassis. Power supply requirements are indicated by the chassis type, with 71 for 115 VAC 50-60 Hz, 71A for 115 VAC 25-40 Hz, and 71E for 230 VAC 50-60 Hz. Late versions (1933) included a shadow meter (tuning aid).
