A switch is thrown ... a motor hums ...giant metal "teeth" start to grind— and it's goodbye to imperfect tubes! That's how "the crusher" works. Now we'll tell you why: To insure uniform, high quality . . . Sylvania tests each tube scores of times— for materials ... for construction . . . for performance. And thanks to a strict "no repair" policy—any tube that fails even one of these tests is sent to "the crusher" . . . completely destroyed! Never a "dud". . . never a second-quality Sylvania tube. For Sylvania— in accordance with this rigid policy — destroys defectives instead of repairing them. Remember this when you buy.
