Silvertone Model 4505 Ivory Plaskon Table Radio (1937)
The Silvertone Model 4505 is a wonderful
example of 1930s streamlined design using
plastic. Together with its companion model
the 4500, in ebony bakelite, they were very
big sellers for the Sears Roebuck
Company. The radios first appeared in
Sears' 1936 catalog, listed as models 4415
(ivory) and 4414 (ebony). However from
1937 through 1939 the designations were
changed to 4505 and 4500. Hundreds of
thousands of these were sold, with a
selling price in 1937 of $11.95 for the ivory
version and $9.89 for the ebony.
Sears claimed in 1937 that this radio took
first prize, as an object of "outstanding
beauty", in the nationwide Modern Plastics
Competition, held in New YorK City.
Furthermore, it was nicknamed the
"election" when it first came out,
purportedly because it was advertised as
ideal for use in listening to broadcasts of
the 1936 presidential election, held on Nov
3rd and won overwhelmingly by the
incumbent Franklin Roosevelt.
The 4505 is a 5-tube ac-powered TRF
receiver that covers the standard
broadcast band from 540-1720kc. The
tubes used are 6D6 (1st RF), 6D6 (2nd
RF), 6C6 (detector), 43 (af o/p) and IV
(rectifier). The circuit is somewhat
unusual in that it employs an
auto-transformer both to step-down the
line voltage (to feed the series strung
tube filaments) and to step it up (to
supply the B+). As a result, the Riders
manual listing for this set cautions that
the chassis is not isolated from the ac
line.
