Snagged a Wavetek 1901C last week. This is a 12" oscilloscope display
(X/Y+intensity input), I was hoping to use it as a point-plotting/vector
display for a couple of little computer projects of mine. (Or maybe
just hooking an Asteroids board up to it... :). It's in pretty good
shape (has more screen burn than I think I've ever seen in a few spots,
though.) I fixed a couple of cold solder joints and it's now mostly
working, except something appears to be going slightly wrong in the Y
deflection or amplification (it's getting clipped/distorted depending on
the gain and input intensity).
Anyone have a service manual or schematic for this thing or know good
sources for such things?
Thanks as always...
