MODEL 606 TUBE TESTER What It Will Do 1. The Dyna Jet Model 606 Tube Tester will test all of the commonly used tubes in general use in radio and television sets. 2. In addition it will test many voltage regulator tubes, thyratron tubes, industrial types of tubes and many of the European types found in modern hi fi equipment. 3. Each tube is automatically checked for shorts and leakage to approximately one megohm. These teste are made from each element to every other element so that all possible combinations of shorts can be detected. 4. Grid Emission, Gas, Grid Contamination, or obscure Grid to Cathode leakage are all disclosed by an exceptionally sensitive grid current check. This test will reveal as little as 2 to 3 microamperes of current in the grid circuit and can be adjusted for a sensitivity of over 100 megohms. 5. Each section of a multi section tube is checked separately- 6. Each tube is checked for quality in a test circuit that determines the full capability of cathode emission under current loads simulating actual operating conditions.
