Northern Electric Baby Champ Model 5002-2

 

Model 5002-2

This model was built by Northern Electric for sale in South Africa and possibly other countries. It was designed to operate on 220-250 volts. The chassis is basically a Model 5002 chassis fitted with a resistive line cord designed to bring the voltage down to the 120 volts required. Of interest is the fact that this model was built for both Aeroquipment and Airotone. The Model 5002-2 appears to have been manufactured only in brown bakelite and ivory cabinets.

In addition some of these radios appear to have been fitted with a cardboard dial insert printed with South African broadcasting stations. It is not know whether this dial insert was used on the Aeroquipment, Airotone models or perhaps a third type of Model 5002-2.

Whether or not the Model 5002-2 differed from Model 5002-4 other than being manufactured for a different company is unknown.

I would like to express my thanks to Mr. Eric van Staveren of Valkenburg, The Netherlands, for bringing this model to my attention. The information provided on this page is derived from examples in his collection. His patience in answering my numerous questions is very much appreciated.

The other chassis type did not feature this metal plate as seen on the Model 5002-2 Aeroquipment back scan below. These type chassis types were also seen in the Model 5002.
