Pincushion adjustments

There may be two controls - amplitude and phase. Pincushion amplitude as its name implies, controls the size of the correction. Pincushion phase affects where on the sides it is applied. Don't expect perfection.

If the controls have no effect, there is probably a fault in the pincushion correction circuitry.

It is best to make these adjustments with a crosshatch or dot test pattern
