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
Two trochotrons (BX2012 and BX2013) added and a pentode (CV2390)
Added CV818 pentode, CV2295 and CV10819 double beam tetrodes, and CV7043, CV7070, CV7075, CV7162, CV7313, CV7353, CV7463, CV8516, CV9507 and CV10440 semiconductors.
CV1345 joins it’s equivalent ARTP2.
Added CV7029 rectifier, CV7041 diode, CV7044 transistor, CV7047 diode, CV7049 diode, CV7062 transistor, CV7071 zener diode, CV7090 zener diode, CV7094 zener diode, CV7170 voltage reference diode, CV7338 transistor, CV8550 diode and CV10688 power rectifier.
Added ARTP2 triode pentode, CV2137 CRT and VCRX399 CRT / unknown device. I cannot find a listing for VCRX399 or VCR399. This device may have been manufactured by Cintel and looks to be a developmental tube.
Added an ACR1 CRT, and a VCR530 to the CV1530 page. Also added two developmental CV389‘s to the relevant page.
