Saw this 12lp4 on our favorite auction sight and couldn't resist since my Admiral's 12 inch went to air (my fault, I pulled the base off of the poor thing when struggling with a stuck yoke) It had the copper pinch seal and I guess I damaged it. I bid and won the tube. It arrived about an hour ago in a box big enough for a 19 inch tube. It had the yoke (stuck like my Admiral), the focus coil and the double ion trap. As the Beltron shows, after about two minutes of being on, IT'S GOOD
Getters are nearly clear but it's good!!! Sorry for the poor focus but the flash would wash out the filament. I hate to destroy the yoke but a won't chance killing another tube. I'll try to disassemble it so it can be used for parts.
