CV2184 / VCRX298 CRT
|
This CRT measures 250x65mm overall and has a 12-pin base |
This is an electrostatic deflection CRT. It has the serial number 3986
and VCRX298 is hand-written on the label. The screen is listed as YYM.36, which decodes to
yellow flash, yellow afterglow, medium persistence. I am not sure what the 36 refers to. The
test data specifies a minimum persistance of 5 seconds but does not give a maximum.
