This is claimed to be the world’s first transistor/portable car radio. Certainly it is the first of it’s type on the Australian market. The cradle was sold as a separate item and is now scarce as many were left in the vehicle when it was sold, particularly if the new vehicle had a car radio and the Ferris was kept as a portable only.

The cradle was mentioned in the Mingay's New Products Index on 8th July 1960 but the price is not advertised.

As a portable, it is extremely heavy at almost 2½ kilograms plus the battery.

The correct battery is a Eveready Type 2364

The ferrite antenna is located in the plastic case extension, immediately behind the dial scale whilst the balance of the circuitry is located inside the full metal case. The power input, when the radio is used as a car radio, is filtered to suppress ignition noise. The ferrite rod antenna can be switched out of use when the radio is used as a car radio.

A common fault with this radio, and also the MKII and MKIII versions, is that the output transistors can fail as it is easy, as a car radio, to overdrive them. 12 Volt supply, dual OC71 as audio drivers and the use of multiple speakers are an invitation to use high volume and thus high loads on these germanium transistors.

This first version lacks of a reverse polarity protection when operated from a car battery which both 134 MkII and 134 MkIII have.

The Mark III model also has a different front panel. The 134 and the 134 Mk II are labelled "EIGHT TRANSISTOR". The Mk III version is labelled "ALL TRANSISTOR". No doubt this reflects the change in the design from an eight transistor circuit to that of a seven transistor circuit.
