Notes

This is a 21 inch television that tunes the 10 Australian VHF channels standard at the time.

The 6CM7 was replaced by the 12BH7 in later production due to reliability problems with the former.  It was recommended that the valve type be changed if the 6CM7 needed frequent replacement.  This required wiring and component value changes.
