Another question guys. Is there any way to adjust the pincushion on a K7000? I know there are dedicated pots on the Wei ya's, but I am clueless on how to do it on a K7000. Any help would be appreciated.

Adjust the yoke.

pin cushion correction compensates for the inherent time lag in scaning the corners of the crt. usually 25" and up - exceptions are the flat crts
displaying a crosshatch pattern will allow scan imperfections to be seen.
such as faults in vertical and horizontal linearity/ pin cushion, convergence ( dots are best for fine tuning convergence)
yoke alignment ( rotation and neck position)
adjust pot(s) for straight VERTICAL lines
loss of correction will give an hourglass pic ) (
overcorrection will bow ( )

The 27" k7000 chassis has an additional pincushion correction board. Similar but different than the add on board seen on 27" U2000/U5000 chassis. I've never seen the schematic for it though for a k7000 and I've personally only seen ONE in person. Good luck. Try a different yoke. That usually does it for me.
