Rodan MG-17F Nixie Tube  
Written by AnubisTTP on 2006-09-26  


The MG-17F represents a point of transitional evolution for neon displays; a short lived period where manufacturers began to switch to flat segmented displays, but still packaged them in tubular envelopes. Unlike other Nixie tubes, the MG-17F does not have stacks of shaped cathodes to form it's digits. Instead simple bar cathodes are arranged to form a seven segment pattern. This tube has upper and lower decimal points, allowing it to be mounted normally or with the leads exiting the top of the envelope.

Despite being a transitional device, the MG-17F saw use in a number of consumer products, most likely due to lower manufacturing costs when compared to competing stacked cathode Nixie tubes.
