How to handle the solderless connector (for USA
and Canada only)
In this turntable, a solderless connector is used to connect
the power cord with the primary lead wire of the power
transformer.
When it is unavoidable to replace this connector for re-
placement of the power transformer, or the like, positively
perform the replacement in accordance with the following
procedure to avoid dangers.
Connector part number
£03830-001 (Assembly diagram No. 64)
Tools
Do not use those (small cutting pliers, etc.) other than
regular tools.
Replacement
. Cut both the power cord and the primary lead wire at
near the edge of the connector to be replaced.
NOTE: Do not re-use the used connector.
. Peel off the coverings so that the respective conductor
tops appear by about 15mm.
NOTE: In the case of stranded wires, twist each wire.
. Adjust the tips of the power cord and the primary lead
wire with each other, then securely insert them into the
connector.
. Secure the nearly equal central part of the metal sleeve
with the second concave (2.0) of the tool for solderless
securing as shown on the right.
NOTE:
Perform
a
complete
securing.
. After solderless securing, check the following four points
shown below.
