Phew. Now that I have the entire regulator board out,
I can visually see the
fuse F1 is clearly blown (and of course it tests open). I could just replace
it, but something obviously caused it to blow. Once I put a new fuse in if
Well, IIRC, there's no current limiting in this supply. If F1 ahs blown,
the fault could be a problem in whatever this supply is feeding (and not
on this board at all).
it doesn't blow, what should I be looking for in
that circuit? Also,
couldn't I just plug 20-30vac from a bench supply into this linear supply
and then check test points in the circuit? Given it's hard to reach
Should be fine.
