the device (where the leads enter the chassis). Stretch the sleeving to its full length. Place
one piece of heat-shrink tubing on each end of the sleeving. Process with the heat gun. Be
careful to focus the heat on the heat-shrink tubing, not the sleeving.
– Cut one 3/4-inch piece of large heat-shrink tubing.
– Feed the large-sized heat-shrink tubing onto the front set of leads of power supply
transformer T51. Position near the base of the transformer (where the leads enter the
chassis). Process with the heat gun. Be careful to focus the heat on the heat-shrink tubing,
not the leads. This cable bundle will connect to the rectifier PWB and left channel PWB.
– Cut one 5-inch piece of large expandable sleeving. Cut two pieces of large heat-shrink
tubing, each about 3/4-inch long.
– Feed the 5-inch piece of large-sized sleeving onto the 5 V windings from the rear set of
leads from power supply transformer T51 (yellow, yellow, yellow-black). Include the
black ground wire from the transformer case. Position one end of the sleeving near the
base of the transformer (where the leads enter the chassis). Stretch the sleeving to its full
length. Place one piece of heat-shrink tubing on each end of the sleeving. Process with the
heat gun. Be careful to focus the heat on the heat-shrink tubing, not the sleeving. This
cable bundle will connect to the left channel PWB.
– Cut one 5-inch piece of large expandable sleeving. Cut two pieces of large heat-shrink
tubing, each about 3/4-inch long.
– Feed the 5-inch piece of large-sized sleeving onto the remaining windings from the rear
set of leads from power supply transformer T51 (red, red, red/yellow, violet, green, green,
green/yellow). Position one end of the sleeving near the base of the transformer (where the
leads enter the chassis). Stretch the sleeving to its full length. Place one piece of heat-
shrink tubing on each end of the sleeving. Process with the heat gun. Be careful to focus
the heat on the heat-shrink tubing, not the sleeving. This cable bundle will connect to the
rectifier PWB.
