The Philco Model 95 Screen Grid Plus
Receiver is to be used only on an alternat-
ing current supply of 50 or 60 cycles, 100 to
135 volts. If connected to a direct current
supply such as is used in some hotels,
apartments, stores and houses in large
cities, the Receiver will be damaged.
Do not insert the attachment plug in
the house socket until connections are
made and the speaker plug and all tubes
are in the sockets.

Tubes
Nine tubes are required, a"s follows:
3IJY224 Screen Grid Tubes, or equivalent
3 VY227 Tubes, or equivalent
2IJX245 Power Amplifier Tubes, or equivalent
I UX280 Rectifier Tube, or equivalent
Remove the large tube shield across the back of the Re-
ceiver by loosening the five screws along the bottom and
lifting straight up on the shield.
Plaee the tubes in t,he correet sockets a^s shown in Figure 1.
After inserting the screen,grid tubes (Vy224), the clips
attached to the wires coming irom the round shields must be
pressed down over the terminal caps on top of the tubes'
Replace the tube shield over the four tubes at the back
of the Receiver and tighten the five screws to hold it in place.
Speaker
The Philco Electro-Dynamic speaker is built to work
with the Philco Receiver. It is connected by inserting the
speaker plug in the special socket at the back left-hand corner
of the Receiver. This socket is shown in Figure 1.
Never turn on the Receiver unless the Speaker plug is in
place in the socket.
Aerial or Antenna
The Receiver is equipped with a terminal post marked
"LOC" which, when connected by a short wire to the post
marked "ANT, " provides a built-in aerial, This aerialoonnec-

tion will be found very satisfactory for the reception of local
and in many cases distant broadcasting. If it is desired to use
an external aerial, do not use the wire link but connect the
aerial wire to the "ANT" terminal post, leaving the "LOC"
post disconnected.
An outdoor aerial, consisting of a single copper wire 50
to 80 feet long, usually gives the best results. However, where
there is no powerful broadcasting station within 50 miles, a
longer aerial may be used and will bring in far-away stations
u'ith somewhat greater volume. The lead-in wire is an active
part of the aerial and the aerial length should always be
measured from the Receiver to the insulator at the far end.
The outer end of the aerial should be as high as possible and
the entire aerial should be spaced well away from trees and
buildings and supported by glass or porcelain insulators.
Good results can also be obtained with an indoor aerial
25fteet or more in length. A shorter aerial usually will not be
satisfactory. If the walls are constructed with metal lath the
"LOC" post connection, described above, will usually give
better results than a short indoor aerial.
Ground
A suitable ground clamp must be securely attached to a
radiator valve or water pipe and the bare wire end inserted
in the "GND" terminal post of the Receiver.
Never operate the Receiver without a good $round
connection.
Use separate insulated wires rather than a two-wire cord
for the aerial and ground connections.

Operating the Receiver
After making the aerial and ground connections, placing
all tubes in the sockets and inserting the speaker plug in its
special socket, the attachment plug on the cord should be
inserted into a convenient wall receptacle. Turn on the
Receiver by rotating the On-Off switch in a clockwise direc-
tion. The pilot lamp should light, indicating that the power
is turned on. (When the On-Off switcll is turned off, no
power is used and the attachment plug need not be with-
drawn.)
wait about a minute after turning on the Receiver for
the tubes to become heated, then turn the volume control
(left-hand knob) clockwise about one-half the total range of
movement. Also turn the " local-distance " switch (right-
hand knob) clockwise, that is, to the "distance" position'
Then turn the station selector (center knob) and different
stations will be tuned in at various points on the scale.
Tune the wanted station accurately to the point where
it is clearest and reduce or increase the volume as desired
with the volume control and the "local-distance" switch'
Never reduce the volume of a station by detuning with the
station selector as this will spoil the tone quality and bring
in static noise.
If an unpleasant amount of static noise is heard between
stations, due to electrical disturbances in the locality or to
atmospheric conditions, it may be reduced by keeping the
"local-distance" switch (right-hand knob) in the "local"
position (turned left) while tuning, changing it to the " dis-
tance" position only when this is necessary to bring up the
volume of a weak or distant station.

PHILCO NADIO lNSTNUCTIONS
Always regulate thc volume by means of the " volume
control " and the " local-distanee " switch - never by detuning.
The automatic volume control incorporated in this Re-
ceiver tends to equalize the volume of all stations at the
sound level for which the manual volume control has been
set. This prevents the blaring of strong stations during tuning
and reduces the fading of distant stations. With the volume
control in a given position, the reproduction will not vary
greatly in volume, even if the tuning is changed from a weak
station to a strong one or vice versa.
When using the " LOC " post connection instead of an
external aerial, try the attachment plug in both positions in
the wall receptacle. Leave it in the position that gives the
stronger and clearer reception of distant or q'eak stations.
