Large 1950's TV Valves

[radioman]

Here's some pictures of large valves in my collection :-

Ediswan 68504 FW rectifier
Mazda P650 battery triode
Cossor 402PENA output pentode
National Union 832A dual tetrode
RCA 3E29 dual beam tetrode
Pinnacle 53KU/GZ33 FW rectifier (distinctive Cossor shape)
GEC GXU50 Xenon rectifier

The GXU50 makes a nice purple glow but probably isn't safe to watch....?

Regards,
Andy
