Tests for Replaceable Components. Check
the following components on TD1 and TD3:
Check transistor Q1 (10, figure 4-13
and 16, figure 4-14) by connecting a
transistor tester for current gain of 100
minimum, leakage, or short.
Check transistors Q2 and Q3 (5 and
4, figure 4-14) by connecting each to
a transistor tester and testing for
current gain of 40 minimum, leakage,
Check capacitors (C1 and C2 (6 and
7, figure 4-13) by connecting each to
a capacitor tester and checking for
leakage and capacitance. C1 must
read 10 microfarads, 25 volts ±5
microfarads, 50 volts ±10 percent.
Check capacitor C1 (10, figure 4-14)
by connecting to a capacitor tester
capacitance. Cl must read 300
microfarads, 30 volts, ±5 percent.
Check resistors using an ohmmeter
for the following resistances:
