! micro-watts of radio signals addition
ally impressed upon them would over
load them as has been many times
stated.
In general there are practically two
forms of using vacuum tubes as radio
frequency amplifiers, |. e. the coupling
transformers may be either tunable or
fixed. The tunable type transformers
are so designed that they may be
tuned, usually by variable condenser.
In the other type the transformers
cover a certain range without tuning.
The latter are broad" and make for
unselective reception.
1t is imperative that If selectivity Is
to be had where radio frequency ampli-
fcation is employed the coupling trans
formers must permit tuning adjustment
by variable tuning device such as a
variable condenser. Because the trans
former is actually tuned to the signal
with this type of radio frequency am
plification, not only great selectivity is
obtained, but greater application Is
likewise secured.
Either a vacuum tube, two or three
electrode, or any Of the many forms Of
crystal rectifiers of high frequency
currents can be used as rectifier, we
are told. However, in reflex circuit,
due to the particular location in the
circuit and inherent characteristics Of
the detector, a crystal rectifier will be
more satisfactory. BY the use of the
proper crystal rectifier an excellent
controlling effect on the stability of
the entire circuit may be had. This
feature is not generally known. but is
demonstrated in the stability of the
circuits using this form of a detector.
Not every crystal rectifier which
might possess high rectifying proper
ties will be found the best for this pur-
pose, due to the fact that the crystal
can be made to provide stabilizing
effect on the reflex action Of the cir
cult. The fixed type of crystal natural
fy requiring no adjustment, If correct
ly designed, affords the best form Of
rectifier for the reflex circuit.
Another point of interest is the fact
that not every audio transformer can
be used in reflex circuit In a reflex
circuit the audio transformer Is asso-
ciated with the radio frequency cur
rents Of the circuits and requires de-
sign and construction differing from
the regular audio transformer.

my friends that the change in my health

YOUNG, 16 Amherst ST., Charleston, sc.
The reason for such letter from Mrs.
Young is apparent. She got well and
is grateful. Recently a nationwide
canvass of women purchasers of Lydia
E. Pinkham' g Vegetable Compound was
made, and SO out of 100 reported that
they received benefit from taking it.
Just because the Vegetable Compound
has been helping other women is a good
reason why it should help you. For

How to Build and Use
Vernier Condenser

This vernier condenser consists Of
a small semicircular piece of .tinfoil
glued TO the panel front and connect
ed to the stationary plates of the va
riable condenser. The rotating plate
of the vernier is small circular piece
Of sheet brass with another piece Of
brass soldered to the center to make
the whole one-eighth inch or a little
ter is drilled hole the size of the
shaft. 1t should fit snugly on the

when the fiux Is heated it soaks
through and finds its way to the pa
ing its proper course and the result
is a weakened signal.
There are three types of Jacks
used in radio circuits. namely, open
circuit jack, the close, or two-circuit
jack and the automatic f1lament light
ing jack. They are shown in the ac-
companying diagram. There are also
a few jacks of peculiar make which
are rarely used.

this as many sections as you require
taps, making each section of ar equal
width. Wind each of these sections
with bare copper wire, then after re-
placing the element. with hot iron
quickly run solder over the turn to
bond them. The rheostat is then
mounted ON the back of the panel, the
leads from the tuner or variocounIer
are soldered to the sections of the
wire and the switch is complete. This
makes very smooth running switch
and is excellent for the purpose in
tended.

About Tubes.

Since the advent of the dry cell
vacuum tube there have been placed
on the market various types of amplify-
ing transformers to be used with these
tubes In fact, in many cases. these
transformers are being used with the
old type six-volt tube. This practice
is all right. but there are six-yolt
tubes with oxide coated filaments
which consume more power than the
regular six-volt tube. The latter type
tube should never be used with trans
formers that are designed for dry-celi
operation. If they are, the result will
be a burned-out simplifying trans
former.

Long-Lived Birds

Compared with other birds, the
wren is very short-lived. its average
span Of life being three years. The
common sparrow Is a veteran beside
the wren. and often lives 40 years. But
there are other birds which attain
much greater ages. Parrots, for in
stance. often become centenarians.
while eagles have been known to live
104 years. The swan is long liver.
There are numerous instances of this

Care in Connecting
Jacks for Amplifers

Where vacuum tubes, and a number
IF steps of application are used 1t Is
sometimes advantageous to be able to
connect in on the detector tube or on
one or more stages of application.
Telephone jacks are great conven-
fence to those who know how to con-
meet them for this purpose. If con-
nected improperly they are sources
Of constant trouble.
Jacks are generally used to shift

Loose Coupler.

The loose coupler set is the most
efficient type for use with a crystal
set. In tuning such a set use close
coupling, that is, have the secondary
completely inside of the primary. Set
the secondary at some rather low
value in inductancc and adjust the
primary switch. Interference and
static may be reduced by loosening
the degree of coupling between the
primary and secondary.

shaft and be just tight enough so that
it will not Jar out Of position. A COM
position handle is fastened TO the NOV
able plate and is long enough to ex-
tend out past the circumference of the
dial. The space between the tinfoil and
the movable plate should be about one
thirty-second inch, but care must be
taken that this arrangement does not
short circuit the condenser. To pre-
vent this, small insulating washer
can be placed on the condenser shaft
so as to be between the stationary
and movable plate on the vernier.

other types which may be wired to
control automatically the filament
current. This arrangement is con-
venient one and results in great saw
ing of battery power.
Wiring the jacks in an amplifier cir
cult is ofttimes difficult problem and
unless the builder has some knowledge
of them 1t is best to leave them alone.
An amplifier jack poorly wired will
spoil the efficiency of the set as a
whole.
1t Is best to avoid the use of flux
or soldering paste when soldering the
connections to the terminals of the
telephone jacks. At times builders
make an untidy job of this so that
