The Original Installation and Operating Manual |
he Trio 9R-59 Communications Receiver was
a product of the 1960s, manufactured by the Trio Corporation of
Tokyo Japan. It was also marketed as the Kenwood Lafayette HE-30
with the same innards but slightly different casing (the Kenwood
brand name was not at that time used by Trio in the UK as it
already existed as a make of food mixer).
The 9R-59/HE-30 was available in kit form at 25gns (£26.25) or ready-built at 33gns (£34.65). These two adverts are from August 1966 and possibly refer to a slightly earlier model, the HA-230/KT-320. I suspect that KT 320 is a typo for KT-230. Or is HA.230 a typo for HA-320?
Reproduced below is the original eight-page A4 Trio 5R-59 Installation and Operating Manual which includes the operating instructions and circuit diagram.
The files are very large (up to 750KB), in order to allow 300dpi printing at A4 size with similar clarity to the original. Click on the thumbnails below, or use your browser's "Save this link as..." facility to download the files.
hese pictures are of the author's 9R-59
purchased in 1967 for the price of 33gns (£34.65). The front
panel is enamelled rather than crinkle-finished. The s-meter is a
later replacement, and the paper strip is a scale for the medium
waveband calibrated in metres, since most long and mediumwave
stations were identified by their wavelength until the late
nineteen seventies.
The large valve at the bottom right, next to the mains transformer, in the picture below is not the original double-diode rectifier. It is a stabiliser valve used in a modification of my own that saw the thermionic rectifier replaced by a silicon one.
