I found ]this thread extremely useful, perhaps someone could indicate which pots correspond on my BD800? Ive had my Barco running pretty stable now for about 2 months (thanks to Roland for the PSU board). Unfortunately my Barco has had an uncharted past life, and Im convinced everything on it is far from optimal so what Id love to know is in what order to set about correcting things. I assume the physical set up is unaltered by internal adjustments - get it square and central. Having got this set correctly I assume Im onto the adjustments around the throat of the tubes? What order should these be attempted in? Ideally could someone provide links to details of how to make these adjustments?
