If I may make a suggestion: A Simpson 260 was great in it's time but
not recommended for troubleshooting solid state equipment. Its
voltage in the ohms mode is high enough to "turn on" a transistor or
diode and thus can cause errors when measuring components around the
device. I recommend a Fluke 87 or the equivalent. It's normal voltage
is low but it also has a "diode" position which does apply higher
voltage when necessary.
Expensive when bought new but many used ones are available. Be sure to
get a money back guarantee.
