Check the focus lead into the red CRT PCB to make sure it has a good
connection. You may have a bad focus / screen block. To verify, temporarily
swap the red and blue G2 leads on the block to see if the problem stays with
the red or changes to the blue.

>>> Pete,
>>> Try the screen adjustment first. This usually takes care of the problem.
>>> It should be done in total darkness-use a blanket to cover the set. From
>>> the manual:
>>> 2-1. SCREEN VOLTAGE ADJUSTMENT (G2)
>>> (COARSE ADJUSTMENT)
>>> 1. Receive the Monoscope signal..
>>> 2. Set BRIGHTNESS to 50% and PICTURE to minimum.
>>> 3. Turn the red VR on the focus block all the way to the left and then
>>> gradually turn it to the right until the retrace line is barely visible.
>>> 4. Gradually turn the control to the left until the retrace line
>>> disappears.
>>> 5. Repeat for green and blue.
