This is the full-restored receiver. The set is housed in a rectangular plastic cabinet and carries just two controls: an on/off volume control and a simple "handspan" tuning control.

There were many small radio receiver manufacturers in Australia until the Japanese began to dominate the radio manufacturing industry in the mid-1970s. In most cases, these small Australian firms made radios for much larger organisations like Myers and similar chain stores. The sets were branded to suit Myers and the various other organisations that did not make radios themselves.

This re-badging has been part of the radio and TV consumer market almost since radio made its appearance early last century. Of course, once a set was opened up, its true manufacturer was usually obvious to an experienced serviceman.

The Aristone M1

The Aristone M1 is one such set that was made by a small manufacturer for a large retailer, in this case Myers. As far as I can determine, "Aristone" was the name Myers used on the radios badged for them but I have not been able to discover who actually made the Aristone sets.

The M1 was a fairly standard 4-valve mantel receiver that came housed in a plastic case. It employs a conventional superhet circuit, with a 6AN7A converter stage followed by a 6N8 as the 455kHz intermediate frequency (IF) amplifier – see Fig.1.

The diodes in the 6N8 are used as the detector and for the delayed AGC system. From there, the detected audio is passed through the volume control and then to the 6M5 audio output valve.

The power supply uses a 6V4 as a full-wave rectifier. This provides around 260V DC at its cathode, which is then fed directly to the plate circuits of all the amplifying valves.
