Beschreibung: Tube and Transistor Tester
Informationen:
                                    Numerous solid-state devices are finding increasing
application in television
and other home entertainment equipment. These devices are also
being used in conjunction with a multitude of tube types to
produce the
hybrid sets.
To be effective in the field service of these units, the
service technician is
faced with transporting a rather cumbersome and costly array
of test
equipment. The Sencore engineering staff is aware of the
problems and
needs encountered in the service industry. In response to
these needs, the
ever popular Mighty Mite Tube tester has been expanded to
incorporate
the features of Sencore's latest solid state device tester,
the TOUCH
TONE CRICKET. Now, in one compact, rugged, easy-to-use unit,
exists
the ability to completely and reliably test the tubes,
transistors, FET's
and diode devices found in modern home entertainment equipment.
FEATURES
* A single instrument for fast, accurate testing of tubes,
transistors and
FET's without complicated set ups.
* Pin elimination switches for greater capability in tube
tests as new
types are announced.
* Full cathode current emission test of tubes.
* Sensitive 100 megohm grid leakage test in addition to
regular shorts
test, all on a large easy-to-read meter.
* Complete test for transistors and FET's including
in-circuit gain and
out-of-circuit gain and leakage with NO set-up or basing
data required.
* Rugged construction throughout, including protection
against overload
for sensitive meter and circuitry.
