In this case Q14802 was shorted.
As for the shop screen:
I have made a wood frame out of 1x4s about 4x4 feet square. We stapled a
white bed sheet over it tightly.
With screw eyes in the ceiling and the frame's corners, I suspended it
above. The screw eyes in the frams have cord tied to them that slips
thru the cieling eyelets and down to the wall where there are tie-offs.
This allows me to raise and lower all sides to properly angle it for a
good focus/convergence while working.Still there are limits to linearity
observation.Good for HV, video,color,etc.
Thanks for the response, all have a good laborday.
