Could be -- while I may sound like I know exactly how it works, as Lou
Costello said "I grasp it, but it keep slipping out of my hand !" :-)
The window circuit clips the ends off the tube, but I'm thinking there COULD
be extra information that is getting through, such as when the DACs should
be charging the caps that store the clip values, that cause the bounce. Or
it could be noise induced by whatever is floating.
If you've already ordered LM319's, I would just wait, put them in, then go
from there. In the mean time print and read Jed's articles. Then have a beer
and read them again. :-)
I remember looking at the BZ schematic, and haveing no idea what the mess in
the center between the X and Y DAC's did. After reading Jed's e-mail, all of
a suddent it went from looking like speghetti to a perfectly reasonable
circuit.
I've come to realize that it's not so much that Vector machines are
difficult, it's that there isn't much to compare them to. Instead of 100
years of radios, you have really just a handfull of machines from 3
companies. To end with another quote, after Jed had replied to my initial
e-mail with the description of the window blanking, all I could think of was
the line from Ghostbusters:
So they don't make them like that any more ?
NO ! No one EVER made them like this ! Either the guy who designed
this either was a genius, or a certified wack-o.
