Unboxing A JBE ★ PL504 TV Line Output Beam Pentode Vacuum Tube

Unboxing a JBE ★ PL 504 television line output pentode vacuum tube. This valve is probably new & in its original box (NOS new old stock NIB new in box). The glass envelope has JBE ★ & PL504 printed on it in white. Printed on one end of the plain white box is PL504. The type PL 504 has a Magnoval 9 Pin B9D base & top connection cap. It has a heater filament voltage requirement of 27 volts & was first introduced in 1961. I don't know who JBE are or were. A rebrander or manufacturer? If you know please leave a comment on this video.
