VFD voltage and current needed Answered
I've a Futaba 4-LT-16 9L big VFD display. Unfortunately I'm not able to find the datasheet or exact details about it.
Maybe I could contact Futaba...
The only informations I found are these two schematics
https://revspace.nl/old/IMG_2239.JPG (but it doesn't match with the 4-LT-16 display)
https://revspace.nl/old/IMG_2240.JPG (not very useful to me)
from this page and this video from the same page.
Could someone help me?
Are there typical voltage and current for the filament (I think it depends from the length and the display dimension)? What about the grid voltage?
