Due to a fortuitous recent find (on the street of all places) we can now go back 40 years, to 1974.
That year started with optimism, with colour TV and FM radio just around the corner after the earlier short-lived dalliances with 8-tracks and quadraphonic sound.
However it ended poorly, with reduced tariffs, a strong dollar and a wages break-out sending local electronics manufacturers to the wall.
The 1974 catalogue reviewed here is possibly one of the last ones containing many long-lost Australian component brands.
One of the highlights is Dick Smith selling Jaycar products (as explained this was when heavy use was made of local distributors, before the 'direct import' days).
Post script: 1974's prime minister who presided over this potent, sudden and ultimately disasterous policy mix (lowering tariffs overnight in order to lessen the then
rampant inflation) passed away last week. While he could and did claim various policy achievements, all sides acknowledge that economic policy was not one of his interests.
