Hi,

can't find any schematics for this module - its a Bang & Olufsun combined
SMPS/Class D audio amp PCB.

The one I have has the exact same fault as this one:

Blown cap (presumably), but no way of finding out what it was.
There are other photos on the Interweb of this board which show the unmarked
device not blown up.

There's about 330v DC across the remains, and my amp module still works
without it.



This is in a powered Studio Monitor Sub, seems these modules are reasonably
popular in this kind of thing - B&O would not sell these to the public,
though I read on a forum while Googling today that they might now, but are
prohibitively expensive.


Any smart guesses what I should be putting in there? One end goes to the
three paralleled resistors which are very low ohmage and I guess current
sense at ground, the other goes to the first pin of the transformer which is
at high HT.


Cheers,


Gareth.
