FROM THE VOLUME
OF
reader
mail
received,
the columns
deal-
ing
with
the Echophone
ECl restoration
project (concluded
in
the November,
1987
issue of Hands -On
Electronics)
were
among the
most popular,
to date,
in the Ellis
On Antique
Radio series.
So,
never being
shy
about capitalizing
on a good
idea, I'm
going to
kick off a
new
restoration
project
this month.
But first,
a
word
to
all the people who
wrote
me in response
to
the two col-
umns
on the
Crosley 50 (January
and
February
1988):
Even though I
devoted
the
last two columns
to
catching up on
the mail backlog,
I
wasn't
able to get
to
the
Crosley letters.
Be patient,
though!
I'm
saving your very
interesting
stories,
questions,
and comments
for
a column
that will
appear in
the near future.
Zenith's
Tricky
3 -Band Dial
Some years
ago,
I happened
to be
driving through
a rural area
of Missouri
on business.
Passing
a likely
looking
antique
store
and having
a
little
time
to
spare,
I stopped
to check
the old -radio
scene.
The
young lady who waited
on
me showed
me a Zenith
BC /SW
con-
sole with
a
very
interesting
looking
round,
black dial. It
had been
for sale,
she said.
But,
now that
she and
her
husband
had
made an
accidental
discov-
ery about
the
dial mechanism,
they
were
going
to keep
the set.
In
response
to my raised
eyebrows,
the girl
reached
out and
turned the
bandswitch.
As
she did so,
I
was
amazed
to see the
dial calibrations
change
almost instantly
from broadcast
band,
through two
different shortwave
bands,
and back to
broadcast band
again.
I couldn't
figure
out what was
happening
until I tried
the operation
myself.
Rotating
the bandswitch
a little
more slowly,
I
watched
a pair of semi-
circular
dial segments
carrying
one set
of
calibrations
flip out of
the
way,
to be
replaced immediately
by a pair carrying
another
set.
The
Zenith 7S232
as
received
from the
dealer. The
set
is 16- inches
wide, and
almost two feet high; the
charred area
around the
speaker is a result
of a
furnace
explosion.
I left
the
shop with
mixed
feelings.
While
I was
really
taken with
the
beau-
tiful
and ingenious
dial
mechanism,
I
was
almost
happy that
the radio wasn't
for sale.
Even
though
our
home isn't
exactly small,
we
don't have
a whole
lot
of space
available
for
console
storage.
Bad
Luck/Good
Luck!
A few
months
later, I happened
to be
visiting
an antique
-radio dealer
of
my
acquaintance
-an
old gentlemen
who
bought
and sold
the sets
as a
retirement
hobby.
I described
the dial
of the
Zenith
console
and asked
if he
had
ever come
across
one. "Oh
yes,"
he said,
"that's
called
a shutter
dial,
and Zenith
made
quite a
few models
using
them."
"Were they
all consoles ?"
I asked.
In reply,
he
led me
over to
a Zenith
table model
the size
of a small
juke box.
It was
easily
the tallest
non -console
ra-
dio I had
ever seen.
And,
though the
mechanism
was
jammed,
it obviously
had a shutter
dial just
like
the one I'd
seen in
the antique
store.
"How
much ?"
I immediately
queried.
But
it
wasn't
forsale
because
the
dealer want-
ed to work
on
it himself!
Disappointed,
I
began
to
wonder
if
I'd ever
come
across
a shutter
-dial
set with
an
owner
who'd
be
willing
to part with
it.
A few weeks
later,
though,
I received
a phone
call
from the
dealer.
It seemed
that,
not long
after
my
visit,
something
had gone wrong
with
the gas furnace
at
his home.
The result was
a small,
but
violent,
explosion
that
damaged
several
of
his old sets.
The
table -model
shutter
-
dial radio
I'd
admired was
among
them
-but was
still
restorable.
He was
moving
to a new location
and
wanted
to
reduce
his stock.
If
I
was
still
interested,
he'd give
me
a good deal
on the
radio.
Needless
to say,
I lost no
time in
getting
out there
to pick
up my
new
acquisition.
Human
nature
being what
it
is, I
didn't
do much with
the set
after getting
it safely
under
my wing.
There
were
too
many
problems
to be solved,
and the
time
never seemed
right
to begin
on
them.
But
the radio's
many problems
and high
interest value
should
make
it
an
ideal
restoration
project
for this
col-
umn.
So let's get
started!
Introducing
the
Model 7S232
Though
the
photos
don't suggest
it,
the Zenith
Model
7S232
has
to be one
of
the
largest
table -model
sets
ever made.
The
cabinet
is
about 16-
inches wide,
and
stands
almost
two -feet
high.
Its
Here's
the
shutter -dial
assembly
that
makes the
radio
so
interesting.
You
may
be able
to
see
the
edges
of the jammed
shutters in
the recessed
inner
circle.
