Subject: Recorder Hardware Question
From: Andreas Stemmer (groovingandi_at_gmx.de)
I've got a broken recorder model here (old recorder 6GB). The broken
part is a small SMD part, but I don't know what it is. I marked it on
one of Phil's recorder photos from the rockbox homepage.
The part is completely burnt, so there's no chance to identify it. If I
follow the traces, I can see that it was connected in series between the
center pin of the dc input and a zero ohm resistor which goes straightly
to the mc34063a dc/dc converter.
So what could it be? My first guess was that it was another zero ohm
resistor, but that doesn't make sense because there are no other traces
which have to be crossed. And we all know that the jukeboxes do not have
any protecting diode. Some kind of fuse? Any ideas?
I repaired it by bridging the crater with a diode and the recorder works
well again, but I'm still wondering what it was.
