The Amplitrex accurately tests hundred of popular tubes, as well as allows us to create our own custom tube tests with regulated power supplies producing actual operating voltages up to 500 volts. The test parameters include: emission, transconductance (GM), …

2016年4月10日 · We have some tips and tricks to help determine if you have a bad vacuum tube when you do not have access to a tube tester.

We can test your tube pairs/quads and rate their degree of matching, and we can take any number of tubes and segregate them by the usual matching parameters (Gm or anode current). This service is $3 per pair in addition to the Standard test.

A tube tester is an electronic instrument designed to test certain characteristics of vacuum tubes (thermionic valves). Tube testers evolved along with the vacuum tube to satisfy the demands of the time, and their evolution ended with the tube era.

Tube testers were designed as a tool for repairmen to detect “bad” tubes … tubes that could be causing a problem in the item that the technician was repairing. Tube testers do a very good job in this role. However, many people do not use a tube tester properly, do not interpret the results correctly, or have unreasonable expectations of them.

The MaxiMatcher is the only tester that allows you to directly compare full sets of output tubes at the same time. The upgraded Matcher II features a snazzy new carrying case, stronger power supply and stabilized measurement system.

2024年12月21日 · Knowing where to get your vacuum tubes tested is crucial for ensuring you maintain the top quality of your audio equipment. This comprehensive guide will provide you with valuable insights into testing vacuum tubes, reliable locations, and …

Knowing how a tube “tests” or “performs under load” is more important for some tube types and situations than others. For rectifier and preamp tubes, test scores are relatively unimportant for basic function, and tubes of different scores can be swapped in and out without consequence (as long as they are working tubes).

2023年8月2日 · Testing vacuum tubes, also known as valves, is an essential skill for tube amplifier enthusiasts and technicians. Vacuum tubes are critical components in tube amplifiers, and knowing how to test them can help identify faulty tubes, ensure optimal performance, and extend the life of your amplifier.
