Hello-
I've only had experience with 30mm diode guns and would think carefully about the conversion. True, the resolution is higher, but you may experience a phenomenum known as "stern waving" especially in high contrast scences.
I once saw a dancing actor dressed in a tux (high contrast scene)appearing on a modified RCA camera converted to diode guns. Sharp pictures, but the strong lag resembled a digital decay effect.
My recollection is that the beam spot size is too fine for the line structure (in this case 480i). You may have different luck with 18mm tubes.
The best advice on pickup tubes came from Bob Neuhauser of RCA-you have to design the electron optics to the scanning standard used. Good advice.
Let the group know how the conversion works out.
