There are two possible modifi ca-
tions; the fi rst increases the attack
time while the second doubles
both attack and decay times.
Modifi cation A
will increase the
attack time from the original 0.35
milliseconds to 5 milliseconds. It
does not affect the original decay
time which is 160 milliseconds.
1. Replace the two 10 k ohm
resistors marked R117 and
R217 with 121 k ohm resis-
tors.
Modification B
will further in-
crease the attack time beyond that
produced by modifi cation A, and
will also increase the decay time.
If you choose to make modifi ca-
tion B, you must also make modi-
fi cation A. Together, modifi cations
A and B produce an attack time of
10 milliseconds and a decay time
of 320 milliseconds.
1. Perform modifi cation A.
2. Replace the two 0.1 µf capaci-
tors C103 and C203 with 0.22
µf capacitors.
