lOr ) The LEFT output transformer leads are connected
next. Carefully cut the blue-and-white. and green-
When cutting transformer leads to correct length,
strip the insulation at the end of each lead to expose
about
114"
of wire. Tin the exposed end, by heating
it with the soldering iron and melting
a
bit of solder
onto it; this wiI1 keep the end from fraying, and
permits a more secure mechanical connection. Meas-
ure the length with a ruler, from the chassis to the
end of the lead..while holding the lead straight out
from and perpendicular to the" chassis. Cut one of
the black leads to 11/
2 "
in length, and connect it to
lug
#4
of· the 5-lug terminal strip. Do not solder;
remember, a connection is only to be soldered when
the symbol (S) is printed after the instruction.

leads to 6" each. and twist them together, as shown

'a~d
closely spaced;' it', is imperative that
" all'connections' to them be made with care. Keep
stripped wire ends as short as possible;' insert them
in the lugs 'up to the insulation; cut off excess imme--
diately' after soldering each connection; check each
time to be certain that nearby terminals and hard-
ware cannot accidenta.Jly be touched. by bare wire
ends,
