Production

The 'quick heating AC table model' radio was designed and made by David Hain, Sydney, Australia, 1951. The acquisition includes circuit diagrams and notes by the donor describing the design and its purpose. In this radio's design David Hain sought to create a new and compelling feature that would set it apart from other radio designs.
'I have been experimenting for some time and have satisfied myself that I have found such a feature. I have built a set incorporating it, and not interfering with the previously mentioned features.'

A small note wrapped around used capacitor stored in the back of the radio revealed the innovation;

'This 500uF, 12 Volt capacitor was replaced (23 June 1991) by a 680uF, 40V Philips component. It had been in my quick heating AC table model radio since I built it about 40 years ago. It had 'dried out' and lost capacitance causing an annoying hum.'
