We can test vintage or newer vacuum tubes at 2.00 per tube (GST included). Our tester is a Mercury 204 Emissions tester that can tell if your tube is good or bad. We do testing 12 - 5 daily except for Wed. Its recommended to call ahead and book an appointment. We are not responsible for damage that may occur to your tubes.  This tester can only tell if your tube is functioning and at what percent. It is a basic test.
