[Boatanchors] Anyone recognize this gear or the tubes?

[Cal Cotner]

Hi all,

      I tend to agree that the equipment is a microwave TWT  
transmitter.  It's possible that the external anode tube on the floor  
was used in a pass tube voltage regulating circuit in the transmitter  
power supply.  Also, there was one manufacturer of such transmitters  
who used a large conventional vacuum tube as part of the control  
circuitry, but I don't remember who it was.
