Although using consumer type parts is a great idea IMHO (cheap &
relatively indestructible), I wondered if using industrial type power
opamps might work.
Can you say "engineering samples"? :)
Lastly, since Zonn has worked out the deflection and HV issues, that just
leaves how
we get the RGB data to the guns. I assume we are going to reuse the neck
board of
whatever monitor/TV we choose to mangle and just bypass all the NTSC/sync
circuits. Or am I missing something really important (again)?
