Before the Whitlam Labor government announced
sweeping changes to the tariff systems covering imported manufactured goods and
components, there was a general agreement in the industry that colour TV sets
would cost somewhere between $1200 and $1500 (ie, approximately 10 times the
average gross weekly wage!). Moreover, there would probably be no more than five
basic chassis designs: Philips, Sanyo, Panasonic, Thorn and Pye.
Of course, the changes to the tariff structure changed this
drastically and these prices were drastically revised. In a bid to level the
playing field a bit, Telefunken, the owners of the PAL patents, enforced a
6-month moratorium on the direct importation of colour sets with screen sizes of
51cm or less, from the date the first official "limited" broadcasts started in
late 1974.
The locally manufactured line-up for 1974 consisted of the
Philips K9, the Kriesler 59-01 (basically an electronic clone of the K9 but with
different board layouts), the AWA/Thorn 4KA (an antipodean-ised version of the
UK "hot chassis" Thorn 4000 series), the Panasonic 2000 chassis, the Sanyo
CTP7601, the HMV C210, the PYE CT25 and the Rank Arena (NEC) 2601 and 2201.
Notably absent were any locally-made models with remote
control, absurd though that may sound now. The problem was that remote control
necessitates a varicap tuner and because Australia has a number of "oddball" TV
channel frequencies that are not used anywhere else in the world, there was
nothing available that could tune in all the Australian channels. There were
some up-market fully-imported European models that did offer remote control but
sales-wise they were problematic, because you couldn’t guarantee they would work
everywhere.
The first remote controls used ultrasonic transducers and were
big, clumsy and unreliable. It wasn’t until the appearance of infrared models in
the 1980s that they started to become standard equipment.
