Added a CV2316 photomultiplier
Added a CV516 cathode ray tube
Added a CV9994 / ZA9 beam tetrode. So far I have not found any data for this valve.
Added a CV5278 aka ZM1020 and Z502M single digit display tube.
Added an NR55 triode to the VR109 page. This valve is unusual in that there is evidence it had a sprayed shield which has been almost completely removed. It carries the NR55 marking and nothing else on the glass, and the serial number 9505. The EVS data for the equivalent CV1109 indicates the valve is not sprayed. The data for CV1000 also says it is derived from NR55, and again says the valve is not spray shielded.
Added a CV2457 corona stabiliser.
Added CV386 subminiature pentode
