sufficient.) In addition, the preferred method of cutting the tubing is to use a so-called “heat
knife.” If such a tool is unavailable, scissors may be used. Note that two sizes of sleeving are
provided—a small size and a large size. Note also that two sizes of heat-shrink tubing are
provided—one small and one large.
– Cut two 6-inch pieces of small expandable sleeving. Cut four pieces of small heat-shrink
tubing, each about 3/4-inch long.
– Feed one 6-inch piece of small-sized sleeving onto the primary leads of the right channel
output transformer, T1. 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 (which may melt if exposed to
too much heat).
– Feed one 6-inch piece of small-sized sleeving onto the primary leads of the left channel
output transformer, T2. 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.
– Cut two 4-inch pieces of large expandable sleeving. Cut four pieces of large heat-shrink
tubing, each about 3/4-inch long.
– Feed one 4-inch piece of large-sized sleeving onto the secondary leads of the right channel
output transformer, T1. Be sure to 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.
