The UV200 was a soft valve, it had a low pressure argon gas filling. At the time soft valves were considered to be more sensitive for the role of signal detection. The filament is pure tungsten and thus this was a bright emitter.
The design of the anode and mounting has evolved with a pressed sheet anode bonded to the side support rods.
This exhibit has the RCA logo and the Radiotron brand.
The 'new' RCA logo with the GE logo on the reverse.
The original box. The RCA label is in place and the company name Radio Corporation of America is clearly present. At this time RCA is still selling General Electric valves.
