How to Test Vacuum Tubes: A Guide for Beginners
To test a vacuum tube, you need a tube tester. First, insert the tube to be tested into the tester and select the appropriate settings, including filament voltage and bias. Next, turn on the tester and allow it to warm up. Then, press the test button and wait for the results. The tester will measure the tube’s emission, transconductance, and other characteristics. If the results fall within acceptable ranges, the tube is considered good. If not, it may need to be replaced.
