PACEMAKER TRANSPORTABLE (1960)

The Pacemaker Transportable was manufactured for H. W. Clarke Ltd by Collier & Beale Ltd in 1960, production ran for 3 years.
This model is part of the Pacemaker Transportable series of radios.

Third in the series of Transportable broadcast band portable transistor radios.

Last of the oak cabinet models.  Has a hole in the rear panel to access an aerial socket, and an earphone socket on the side.  These features were not present on previous models.

The brass nameplate on the front has TRANSPORTABLE, as does the inner transistor layout label and the service information

The Pacemaker Transportable is part of the Pacemaker Transportable series of radios.

The Pacemaker Transportables were battery portable transistor radios from Collier & Beale.  The first model appeared in 1957 and was world-leading in that it had a (possibly the very first ever) transistorised RF stage. 

 

The first 3 models were released in an oak cabinet, with the original model being easily identifiable as it has a brass backing plate behind the Pacemaker logo on the front and a hinged back panel.  All subsequent models had just the logo with no plate and a slot-in back panel.

 

The dial cover should be totally transparent, but most are opaque from time / UV damage, dust and scratches... if the cover isn't totally broken and gone.  Underneath is the dial plate with North and South Island stations separated onto their own sides.

 

The last 2 models came in red or cream material covered cabinets of a similar size to the earlier releases.

 

Interestingly, the original models bore a striking resemblance to the Sony TR-72 (externally, at least).

The radios in this series are:
1957 Pacemaker Transistor 8 Transportable
1958 Pacemaker Transistorised-58 Transportable
1960 Pacemaker Sportable
1960 Pacemaker Transportable
1963 Pacemaker TP63 Transportable
1964 Pacemaker TP64 Transportable

General Construction Notes for Collier & Beale Ltd:

Model numbering followed no real sensible scheme until around 1940 - and prior to 1934 apparently no model numbers were assigned at all.

From 1940 a 3- or 4-digit system was employed where the first digit indicates the number of valves, the second digit is the number of bands and the third is the year of manufacture.  From 1950 the last digit became two digits, eg: 5151 is a 5-valve broadcast-band only from 1951.

From 1957 model numbers were replaced with model names, ie the Pacemaker Buffalo - which makes the year of manufacture hard to determine unless service info is consulted (although C&B often released service info after the radio, and the date on the service info was for its release, not that of the model.
