station based in Wagga Wagga
and broadcasting to the Riverina

The station began as 2CO in 1931 originally based in Albury

The transmitter originally installed at 2CO was a STC
6.5/7 kW model manufactured in Sydney from imported components. The final output stage had a pair of water-cooled 4220-B triode
s. These needed a 12,000 volt supply. This was driven by a pair of type 4015-A triode valves cooled by air. The power supply for this was only 5,000 volts. The power supply was three phase using three 4222-A vacuum diodes also water-cooled. The water cooling was at a rate of 37 litres per minute and had a 450 litre tank and heat exchanger outside the building.
