Adjusting the peaking

To adjust the Peaking potentiometers, do the following:
1.

Using MS Paint and a spreadsheet, create a testing image

on your PC desktop that includes squares, lines, text, and

gradations of color.

Use the illustration below as a guide.

2.

Adjust the LF (low frequency) potentiometer until the

image is free of streaking. When the LF is over adjusted,

the streaking is the same color as the image, as shown

below.
