NOTE: Make up a 6-8 turn, 6 inch diameter loop from insulated wire, connect to signal- generator leads, and place near radio loop.
For proper adjustment of the oscillator trimmer, fully open the tuning gang and insert a . 006 inch non-metallic shim between the heel of
the rotor and the top of the stator plates. Close the tuning gang sufficiently to hold the shim in place, and then remove the shins without
disturbing the gang setting.

ALIGNMENT PROCEDURE
General — Allow set and test equipment to warm up for fifteen
minutes before starting the alignment.
Dial Indicator — Before alignment, the chaI knob should be set as
follows: with the condenser gang plates fully meshed, the first
knob marking ( past the 550 KC point) should be in line with
the gold spot.
Output Indicator — Connect a 1000- ohms- per- volt a- c voltmeter or
an oscilloscope across the voice- coil terminals.
Signal Generator — Use an AM r- f signal generator. Connect the
ground lead to B—, and connect the output lead as indicated in
the alignment chart.
Output Level — Attenuate the signal- generator output throughout
the alignment so as to maintain the output below . 4 volts.
Radio Controls — Set the volume control to maximum. Set the
tuning control as indicated in the alignment chart. It is recom-
mended that a- c power be used when aligning the radio.

motor switch acts as the amplifier
on- off switch. The switch on the
volume control ( as used in the
other models) is omitted. This will
slightly
modify the AC cable con-

Note: In later production sets, R9
is a normal 100 ohms resistor. For
replacement purposes, part number

SERVICE BULLETIN FOR PHILCO THREE- SPEED
CUSTOM AUTOMATIC RECORD CHANGER
M-25
CARTRIDGE AYD NEEDLE CHANGE PROCEDURE
If loss of sensitivity, distortion, mistracking, or ex-
cessive record wear occur, the needle and cartridge
should be checked and, if necessary, replaced.
Defective or worn needles may cause mistracking,
distortion, and excessive record wear. Since most
needles are composed of very hard, brittle materials,
they are subject to chipping if carelessly handled. A
chipped needle will act as a chisel and cut away the
impressed variations in the record grooves, thereby
destroying the record. This action is usually indicated
by a deposit of fine dust on the surface of the record
after the record has been played. A worn needle will
sometimes result in mistracking and usually in the
loss of the higher frequencies.
Occasionally poor connections to the cartridge con-
tacts, corroded contacts, or defective leads may create
the suspicion that the cartridge itself is defective.
Therefore, check for these conditions before assuming
that the cartridge must be replaced.
Cartridge Replacement
To replace a defective cartridge, or to exchange one
type of cartridge for another, perform the following
steps:
TP3•2852
Figure I
1. Hold the tone arm rigidly on the tone- arm rest
with the right hand, and press the lower exposed side
of the cartridge to the right with the forefinger of the
left hand, as shown in figure 1. Then press downward
lightly on the SELECTOR SWITCH in the top of the
tone arm, using the thumb of the left hand, until the
end of the switch lever disappears below the top sur-
face of the tone- arm head. The cartridge can then be
removed completely from underneath the head.
2. With the tone arm on the tone- arm rest, insert
the cartridge into the head of the tone arm so that the
guide channel ( see figure 2) on the cartridge is facing
inside, toward the turntable. Position the lever on the
cartridge in the center of the tone- arm head, and
gently push upward on the cartridge until it snaps
into position.
When the cartridge is in the correct position, the
lever will extend slightly above the head. When prop-
erly installed, the cartridge cannot be pushed out by
pressure on the top of the lever.
The dual- needle cartridge, when properly installed,
should move freely forward and backward to enable
the selection of either Standard Play or Microgroove.
The " Phonorarrta" cartridge is automatically locked
into the 45- LP position when properly installed.

aligning the needle, press on the shaft of the needle
to seat it firmly in the cartridge.
CAUTION: Do not press upon any part of the
needle except the shaft. Also, do not twist or turn the
needle in any way that may cause damage to the
crystal within the cartridge.
The replacement dual needle may be ordered by
Part No. 45-9784.

Needle Replacement
To replace a needle in the cartridge, perform the
following steps:
1. Remove the cartridge from the tone- arm head as
explained above. ( Do not attempt to replace the
needle with the cartridge in the tone- arm head.)
2. Gently remove the needle by pulling straight out,
using tweezers or a knife blade under the heel of the
needle. See figure 3.
3. Before installing a new needle, observe that the
keyway in the needle socket will allow the needle to
be inserted only one way. See figure 4. After properly
