Hi everyone,

Thanks for your help so far.  I've been really busy in the last few
days, so haven't had any time to open up the AN1x and see if there's a
lot of dust inside.  I might get time this week, but I'm doing some
freelance work at the moment, and it's taking up a lot of time (and my
girlfriend is taking up the rest of it)!

I have (and have always used) the standard power supply that came with
my AN1x when I bought it.

I don't have the necessary equipment to test the power supply here, so
I'll have to wait until I go home for christmas (my dad has some testing
equipment that I can probably use).

I'm still fairly sure it's a heat-related problem (just because of the
way it takes time before the first reboot happens, but then reboots
continually until I turn it off for half an hour or so).  This still
seems (to me) that it's a heat related problem, otherwise why does the
AN1x not reboot until it has been switched on for a little while, and
why does it continually reboot until it is switched off?

Actually, I just remembered that before the rebooting problem happened,
the first thing I noticed wrong was that the sound from the right
channel seemed to have gone completely.  Further checking revealed that
it was there, but very faintly and distorted.  I thought it might be the
audio cable, so I tried everything I could think of to check that
(different cable, different mixer channel, etc).  The sound was fine
from the headphone jack, but was not working properly from the main
outputs. Anyway, a factory reset seemed to sort things out (but maybe it
was because I switched it off for a while too?) so I didn't worry about
it any more.  This was just a few days before the rebooting started, and
I had almost forgotten about it.

Sorry I didn't reply sooner - I've just been trying to find enough time
to open up the AN1x, but it never came about.  I'll get back to you as
soon as I manage to solve the problem (or get stuck again)!

Cheers for your help so far, and if I do end up having to put a heatsink
on the AN1x, I'll document it online somewhere.

~Dave
