Page 7: How Does The Orange Vt1000 Differ From Other Commercially Available Valve Testers
ALVE ESTER -1000 VT1000 D RANGE IFFER THER OMMERCIALLY VAILABLE ALVE ESTERS Commercial valve testers have been available, almost since valves were invented, incorporating many excellent techniques and designs over the years. However, the vast majority have a number of common features, which we considered to be a barrier to the modern valve user namely: ... - Page 8 We are passionate about valve technology and our aim throughout has been to make the Orange VT1000 a sophisticated, modern, truly portable valve tester which is primarily useful but also stylish,...

Page 9: Before Using Your Vt1000
EFORE SING With the VT1000, Orange has designed a compact, safe and simple alternative to the large, dangerous and complicated valve testers of the past. However, despite its small size the VT1000 Valve Tester is a highly accurate and sensitive piece of test equipment, and should be treated as such. - Page 10 ALVE ESTER -1000 3. Do not test hot or warm valves. The VT1000 uses high voltages to ensure accurate readings from the valves which are tested with the correct voltages as stated in their manuals. Under testing, the valve will become warm and this heat will alter the impedances inside the valve. If the same valve is then repeatedly tested before being allowed to return to room temperature, or if a warm valve is tested having just been used (e.g.

ALVE ESTER -1000 SING ALVE ESTER Step 1: Decide what valve you would like to test and identify what valve test socket is required for the test. Octal power valves such as EL34s, KT66 etc… use valve socket 1 ... - Page 15 ALVE ESTER -1000 Step 5: Once the test completes and the green, yellow or red indicator lights, then the test is finished; however, as valves may get hot during the test, we recommend that you make sure that the glass envelope is cool before attempting to remove it.

Page 16: Valve Matching Value
ALVE ESTER -1000 ALVE ATCHING ALUE ALVE ATCHING ALUE A ‘matching number’ indicated by the LED(s) at the end of the test, is based on a combination of measured parameters to give an indication of how the valve will perform, according to its typical function in an amplifier. - Page 17 ALVE ESTER -1000 ALVE ATCHING ALUE OUBLE RIODE ALVES Double triode (pre-amp valves) have two valves inside one envelope i.e. an A & B side. After the VT1000 has tested a double triode (providing that the valve passes) two matching value LEDs will illuminate.
- Page 18 ALVE ESTER -1000 ALVE ATCHING ALUE OUBLE RIODE ALVES … ONTINUED Due to the concise nature of the LED display, occasional very slight matching value variations may be observed in some pre-amp valves. For example, one side of a pre-amp valve may display a higher or lower value on a subsequent test (no more than a single digit).

Page 19: Faq
ALVE ESTER -1000 Why do I need a valve tester when I can test old or suspect valves in an amplifier? There are several reasons why old or suspect valves should not be ‘tested’ directly in an amplifier. Valves can have many different fault conditions; some are obvious, such as internal arcing or inter- electrode short circuits. - Page 20 ALVE ESTER -1000 Some faulty valves fail at different stages in the test, is this normal? Yes, the VT1000 automatically performs many tests on the valve whilst the LED bar-graph elapsed time indicator is running. If the valve fails at any point, the test is automatically terminated and the red ‘FAIL’...
