Above, the chassis as
it was when I bought the radio. The
crooked rectangular object beneath the upper spindle is suspect and
clearly not original. It is in fact a "Wireless" combined leak resistor
(2M) / capacitor (200 pF). This combination was
removed and replaced by an original capacitor. The grid
leak resistor was placed at the other side of the chassis,
where it belongs. The crooked transformer
is a Lemouzy type one; this
transformer was removed and replaced by an original Ducretet
transformer (see picture below).
horizontal wooden brace behind the metal front
was missing. In the middle of this this brace,
there is a brass snap connection for the lid.
The brace was replaced by a new one with the
lower half of the original Ducretet snap
connection. This work was done by furniture
restorer Wiego Bergsma, Utrecht. For use with a frame antenna, the left
coil has to be removed and
replaced by a special plug.
Radiospire No 48R (200/700 m) and
transformateur No. 225T came with the radio.
Transformateur 225T (long wave) can not be used
together with Radiospire 48R. Coils 70T and 48R,
shown above, are a better combination.
