The right knob, actually, controls the horizontal hold. Not the position.

Opening up the case, I find the following pots:

V-lin
H-cent
V pos1
V pos2
Focus
Screen
sub cont
G cut off
R cut off
R drive
B cut off
B drive

(no, didn't see a G drive)
...so, anyone have detailed descriptions of what all these do?

I assume H cent will fix my particular problem.  Also, I find that my
"white" is distinctly on the yellow side of white. Logically, increasing
the percentage of blue in the picture would correct this, but
should I fiddle with 'B cut off' or 'B drive'??

...I didn't adjust any pots yet, as my girlfriend was present and
kept telling me to 'close that thing back up or you'll get yourself killed!'

any help (particually from people who have done this before) is
appreciated.
