replacement see ~i~, 5-2,
Tektronix Part Number 003-0619-00. If an extracting tool
is not available, use care to avoid damaging the pins. Pull
slowly and evenly on both ends of the integrated circuit.
Try to avoid disengaging one end before the other end.
Interconnecting Pins
Several methods of interconnection including square
pin and coaxial cable, are used to electrically connect the
circuit boards with other boards and components.
Coaxial Cables
If the coaxial cable to the FUNCTION OUTPUT front
panel connector is damaged replace the entire cable
assembly. Other coaxial cables in the AA 501 can be
replaced or repaired as necessary.
Square Pin Assemblies
See Fig. 5-1. These pins areof variouslengths. They are
attached to each other with a plastic strip. To remove
them, simply unsolder from the circuit board.

Multi pin Connectors
The pin connectors used to connect the wires to the
interconnecting pins are clamped to the ends of the wires.
To replace damaged mutlipin connectors, remove the old
pin connector from the holder. Do this by inserting a
scribe between the connector and the holder and prying
the connector from the holder. Clamp the replacement
connector to the wire. Reinstall the connector in the
holder.

ment side covers. Next remove the six screws attaching
the top cover and rear panel as shown in Fig.
