kx250rider... Did the FD210 use the flat or the curved screen version of the tube?
I have posted a few more pictures of the tubes, perhaps showing the screen and construction differences more clearly.... Picture #1 and #2.
Also a comparison to the Telefunken D5-100V, used in a Sinclair portable. The D5 is an all electrostatic deflection CRT (honey, I shrunk the 7JP4!). Pictures #3 and #4.
Also, I apologize... I should have posted this thread on the "Rectangular Tube and Solid State" Forum... I thought it was color only.
