Here are all
the original pages from the 1952 Practical Television magazines
which describe how to build the ARGUS television receiver, using
a 6-inch ex-WD tube of your choice and lots of EF50s and SP61s.
The articles are set out here in the correct order.
Simply click
on the small pictures to see that page at higher definition. Ensure
your browser does not resize the bigger images 'to fit' or you'll
find them hard to read. Alternatively, right-click on the small

Cabinet building
details were not included although specially made cabinets were
available from Messrs. Tallon, of Rugby. In any case the design
is simple and should not be too difficult for a competent person
to produce today.
Only build
this televisor if you thoroughly understand how to handle very high
voltages safely. This unit incorporates a mains power transformer
producing 2000 volts with a relatively low source impedance - one
touch will kill. Serious prospective builders would also be well
advised to look at my sheet of modifications found necessary HERE.
The 'Argus'
really is electronic television at its most simple... Enjoy !
