More or less any consumer grade switch mode power supply! The Draytek in
question was a, can't remember the blinking number but was a rack
mounted jobby.

Had a TV the other day the caps after the rectifier where shot oddly
enough read fine on a PEEK Cap tester but a couple of new 105 deg ones
sorted that.

And for that matter any test gear of a certain age, power supply caps
change them they don't last forever!..

Mine has a wall wart.  Don't think its a switched mode johnny.

Indeed. I had a valve radio from the 1950s that needed a new cap on the 
main HT supply.

What does the wart state it outputs?  If it outputs regulated DC it is 
/most likely/ a switch mode supply.

Most wall warts have been switchers for a rather long time.  The days 
of the wart being just an AC transformer in a plastic case disappeared 
years ago.

A *small* DC wart is surely a switched mode supply.

Indeed.  Size is a sure indicator.  The old transformer warts were 
limited size wise by how small a 50hz or 60hz transformer can be and 
still operate properly.  If the wart is smaller than the old 
traditional approximately 5cm x 5cm x 5cm cubes (at least that was the 
approximate size I remember for US 60hz 120v transformer warts) then it 
is most certainly a switched mode supply.

Weight is also another very reliable indicator.  If it does not feel as 
if it is filled with lead, it is a switcher.

in the past 20(ish) years I've changed dodgy electrolytic capacitors in 
two set top boxes, one Samsung TV and a Netgear router.

I've done plenty as well - two Topfield PVRs, at least one PC 
Motherboard, and quite a few Power Supply Adapters for starters. But I 
do not think the Draytek has a problem here.

Draytek cost 3 tjmes as much as a cheap Netgear or D-link: They can 
afford to use good components

I still have a CISCO SOHO router. but it was a re badged unit from IIRC 
Linksys

Got fearfully hot , Never missed a beat though

I had my Topfield apart twice for capacitors. Initially is was thought 
that only a couple of values had problems but then a couple more years 
down line it was found that other capacitors in the power supply failed.

The failure was progressive and caused some power supply output voltages 
to rise significantly and if left too long took a out a tuner 
transistor. Luckily all of this was fully documented by users and the 
instructions for repair could be found on line.

Indeed - there is a guy (still) selling complete Topfield PSU reburb kits...

   Had to do that in ONE 18-port switch once. But ONLY once.

   Fortunately I tended to save caps from other old equipment
   so I actually had good replacements at hand.

   However I don't think the poster's probs arise from crappy
   little hardware issues.

   As for overheating ... I posted elsewhere about how easy it
   is to turn packaging material into a 'cooling box' for one
   or several little computers/drives/etc. Amazon has a huge
   selection of fans, many of which will operate off of a
   simple USB port - but you can always splice in an external
   wall-wart if you wanna save yer USB power.

No, I dont think they did.

Well the weather has retreated from 'Texas' to mere 'South of France'

No further crashes have happened since re-flashing the firmware

I wish it's not a Y2K problem that's not
yet fixed. Did you update to the latest
firmware?

   Um, we're pretty much past Y2K .....

   Funny movie by that name though  :-)

   Anyway, Linux started pretty small and compact
   and writ mostly by a relative few connected
   people.

   It's NOT like that anymore.

   And, alas, the logs often DON'T pin down The
   Problem much anymore - at least not in any
   comprehensible fashion. It's become kinda like
   the old Amiga "Guru Meditation" messages ...

   Which is why I trashed my A-1000. Paid a lot
   for it too, high hopes .....

   Yea, later versions WERE better, but I'd blown
   my wad already. X86 Forever thereafter.

   So ... sorry ... if your distro has gone rotten
   then you need to install a new one and hope for
   the best. Still better than Winders World though.

   If you can, write a "My Important Shit" script,
   BASH or Python, that will export YOUR custom
   stuff to a zip archive or whatever. New distro,
   then unzip all the shit to its original paths.

Yes, village Idiot, I did that months ago.
