Vintage 1965 GE short bottle 6L6GC tube. Used, tested. I only have one. $30.
Getter flashing (the "chrome") on the top and side looks great, this tube should have lots of life left.
Made in USA. “LU 188-5” means that the tube was manufactured in August of 1965 at GE’s Kentucky factory.
Tests 110 with zero grid emissions and no shorts on my B and K Dyna-Jet 606 emissions type tester. Minimum good is 65, max is 120 on this tester.
