Dynacord Powermate 600 mixer amp , 2006

Supposed to have only a minor problem for repair but there is obviously
(also) a totally black shapeless lump , presumably remnants of a burnt out
capacitor. Marked C17 between F1 and F2 low power rail AC fuses. Anyone know
its value? probably about 1nF, too low a voltage rating? or because it lies
over a power rail track between D17 and C7, coating burnt off. Loads of
these mustard yellow globular Cs around the board

The output relays seem to present a short to the speakers in powered off
mode, have not got to the solder side of the board yet to explore.
RoHS construction, of course may present other nasties when I get there, not
originally forseen.

According to the schematic, C17 is 0.1uF. If you would like a copy of the
schematics, mail me off-group with a valid address that you accept stuff on,
and I'll send them. The sheet that the cap is on, is 372kB. The whole manual
is 2MB. All in pdf.
