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.
