This is one of three radios
which belonged to Paul Ogden
who never got round to fixing them. When I received it the radio was in
poor
physical condition but was working. The scale markings on the glass had
been washed away, the cream paint was badly damaged exposing the brown
Bakelite in many places and when I tried to tune the radio I broke the
dial cord as the tuning capacitor had seized solid over most of the
range. The grease in the variable capacitor bearings was washed out
with white spirit and re lubricated and the dial cord replaced.
The loudspeaker grille cloth has been washed, dried and glued back in
place, the back cover was removed and washed and allowed to dry over a
couple
of days between newspaper under a very heavy weight. I touched up the
scratches in the paintwork and the following day completely brush
coated the case with a satin oil based paint.
Surprisingly I found that all the components below chassis appeared
to be original and did not need replacement. I discovered by
researching
the internet a picture of a similar model so was able to print a
paper scale which I glued to the plate behind the glass.
