Are you looking to test old vacuum tubes? A vacuum tube tester can help determine if tubes are still functioning properly or need to be replaced. Here are some frequently asked questions about vacuum tube testers:
A vacuum tube tester is a device used to measure the quality and operating characteristics of vacuum tubes (also called thermionic valves or tubes). It tests if tubes are still good, weakening, or completely bad.
A vacuum tube tester applies voltages to the tube and measures the currents. It detects issues like shorts, leaks and quality of the tube's electron emission. Most testers display readings on meters or provide pass/fail indications.
Most general purpose testers can test common tube types like receiving tubes, power tubes, CRT tubes and more. Specialized testers may be needed for uncommon or obsolete tube types.
You can search online for repair shops, electronics stores, hobbyist stores and antique stores near you that offer vacuum tube testing services. Some audiophile and vintage electronics communities may also have testers for shared local use.
Most shops charge around $3-5 per tube for testing. Some may have minimum fees or bundle pricing. Be sure to ask about pricing when contacting local tester options.
