EKCO K18 Battery Eliminator For Sale $66inc GST

EKCO K18 Battery Eliminator, 1929/30 was used to replace the 2 x 45 volt batteries that ran the battery radios. You still had the batteries for the valve heaters and this unit could recharge those batteries for 2v, 4v and 6v. I tested this unit under load and the voltages were quite fair. But with this crude piece of equipment I regard it as electrically unsafe and have disconnected the mains twisted cord from the transformer inside and have fitted heat shrink over the ends and the same at the plug end. This unit could be made safe with electrical insulating materials to prevent the exposed live parts from possibily coming into contact with the metallic body.

This unit is being sold as a DISPLAY ONLY and any work should be done by a licenced Electrical Contractor. There is paperwork available for it. You can see in the bottom right picture how far diodes have come. The transformer and inductor tested ok and I remove the 2 resistors and polished the variable clamps.
