No signs of bulging or seepage.
I was just taking a closer look at the board a moment ago under a glass
and spotted something that requires further investigation. Going to have
to get my stereoscope out of storage for this one. Tiny clusters of what
look like *very* fine gauge enamel copper wire clearly bridging across
vias in various points around the board and obviously not *supposed* to
be there. If they turn out to be conductive, I could be in business!
Don't want to get my hopes up on this one, though. Probably just a false
alarm but *definitely* requiring closer examination with something more
powerful than a glass....
Turns out to get the caps out of circuit requires a 6mm ring spanner
which I shall have to procure from a local emporium tomorrow when they re-
open. Fortunately I already have a 13mm one for the other ends.
