1.
The
Plugbutton
marked
"120-200 microsecond" was removed
and
replaced with a 100 K
variable resistor
(RI07).
2.
Relay K101 was
mounted
in
the electronic chassis. (See Note 5 on
Schematic
30095-105.)
3.
A .20
microfarad
capacitor was
connected
across
the
KI0l
relay.
4.
A 47
ohm
resistor
(RI28)
and
a rectifier
(SR102)
was connected
in
series
with
pin
#3
and
pin
#6
of
the
]104S.
5.
Capacitor C102 was
changed
from
.006
microfarad
to .0082 microfarad.
