Notes

 

The Globe DuoDyne Model 900S has a more utilitarian, less ornate case than the Model 900 but offers slightly enhanced electronics.  It allows for the interception of the audio signal at either the fourth or fifth tube in the signal string, for either headset or speaker signal, respectively.  Simple three-knob tuning, with dial markings 0-180.  All three battery voltages can be momentarily monitored on the voltmeter.

Net weight (2.2 lb = 1 kg) 14.2 lb (14 lb 3.2 oz) / 6.447 kg
