Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270°C during
repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering or
unsoldering.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

Tape Speed Adjustment
Procedure:
(FX277)
1. Playback WS-48A (tape center part) and adjust RV601 so that
the frequency counter reading becomes 3,000Hz.
Standard value : 2,985–3,015Hz
2. Playback WS-48A(tape top and end) .
Check that frequency counter reading is within ±1.0% of the
reading of step 1.
(FX467/FX467ST)
1. Playback WS-48A (tape center part) in the FWD state and ad-
just RV601 so that the frequency counter reading becomes
3,000Hz.
Standard value : 2,985–3,015Hz
2. Playback WS-48A(tape center part) in the REV state.
Check that frequency counter reading is within ±1.0% of the
reading of step 1.

2. Demagnetize the playback head with a head demagnetizer.
Do not use a magnetized screwdriver for the adjustments.
3. These measurement and adjustment should be performed with
the rated power supply voltage (2.5 V) unless otherwise noted.

NOTE :
• Due to standardization, replacements in the
parts list may be different from the parts
specified in the diagrams or the components
used on the set.
• -XX, -X mean standardized parts, so they
may have some difference from the original
one.
• RESISTORS
All resistors are in ohms
METAL : Metal-film resistor
METAL OXIDE :Metal oxide-film resistor
F : nonflammable
• Items marked “ * ”are not stocked since they
are seldom required for routine service. Some
delay should be anticipated when ordering
these items.
• SEMICONDUCTORS
In each case, u : µ, for example :
uA.... : µA.... , uPA.... : µPA....
uPB.... : µPB.... , uPC.... : µPC....
uPD.... : µPD....
• CAPACITORS
uF : µF
• COILS
uH : µH
