I thought I better start a new post instead of 'jack the DAC thread.
I noticed recently that depending on the angle of my xpander i.e.
flat, versus angled on a rack where it normally sits, there is
flickering in the power switch light. There is more flickering the
more horizintal it is, and none at all when it is vertical.
I don't know if it's coincidence that it seemed the only trouble I
ever had with tuning (the filters, not the voices), was when it was
flat. All the filters passed, but the they were never completely when
self-oscillating (they are when it's more vertical). They kept being
out of tune on two voices in particular, so I thought it might have
been a filter chip issue, but then I put it back on the rack and had
no problem.
More than anything, I am worried the flickering is indication that
something is somehow "moving" around... something power supply related:/
I plan to have the whole thing pre-emptively serviced (recapped) soon
anyways, but does anyone have any clue what the flicker might be a
sign or, or the result of?
