Dimensions (WHD) 150 x 95 x 40 mm / 5.9 x 3.7 x 1.6 inch

The front panel is clear perspex. This model came with a leather carrying case.

Alternatives for the Audio Driver and Output Transistors are listed as CK872 and 2 X CK878. All transistors are mounted in sockets.

Advertised as "Australia's First Pocket Portable" in February 1959 and was only on sale for a very short period.

This radio is unusual in that it uses a circuit board but not a “Printed” circuit board. The board is punched or drilled and all wiring is “point to point” on the “non-component: side of the board. There are actually three components on that side of the board. When the board is removed from the case, the tuning dial remains captive in the fascia.

Colours avalable: Blossom Pink, Coral, Cherry Red, Chinese Red, Dark Green, Grey, Black, Lime, Tan, Lawn Green & Charcoal.

If ever any radio can be called a "Transision Model", this would qualify. The Circuit Board is drilled and there is no printed copper, just point-to-point wiring. The larger Astors of this era, E.G. the HPN, used tag strips and point-to-point wiring whilst all the later "pocket" radios that are the same size as the CPN use printed circuit boards. The wiring from the rod antenna to the board is over-long and flimsy. Along with many (most?) transistor radios of this era, my example has suffered from leaking batteries.
