Mine was on standby most of the time.

Herewith a paraphrased version of what a (professional engineer) user wrote on March 3rd. 2009 - see http://forums.rokulabs.com/viewtopic.php?t=19088

[i]"As a professional engineer with many years experience I consider that the Soundbridge R1000 radio is a unit where the power supply is bound to fail on a regular basis.
This being caused by a total lack of thermal management, which is mainly due to the plastic box, tape and sealant that surrounds the box of components that house the PSU, which remains permanently powered ‘on’, and thus runs at an excessive temperature.

My radio died after 14 months. It had been on standby pretty much everyday during that period except for 2 or 3 holidays (during which it would be unplugged from the wall for about 2 weeks).

Daily use for about 1 hour, more at the weekends.

Currently with Pinnacle in Germany for repair under warranty.

Seems to me that the radio would live much longer if you would not let it in standby when not used. Instead shut off the power!

That is correct.
I had one of the first SB Radios (I think from 2006) running here for years and a few months ago I removed the PSU. It was OK, but I was worried if it dies that it kills one of the amps. And this unit was all the time really off power when not in use.

I've just been looking through my shelves and stumbled across my good old SBR R1000. Which had ended up after 1+ year of great continuous service with a blown up power supply. All other components are still happy to go. Is there in the meantime a reliable power supply available to suit? Or would I be better to abuse some switched power supply(ies) to replace the blown up unit? I noticed the amps and the display unit do work happily at lower voltages. Has someone experimented with lowered voltages? In my case 8v/12V seemed to do the job pretty well. Maybe not as many neighbours as before would notice the alarm clock but that might be something I could live with. Any contra indication to "undervolting" ?

I used a 12V/2.5A power supply for both voltages and that works for years now...

Sounds interesting, you kept it internal? I would have expected 12V on the processing board to increase the heat internally. Do you meanwhile keep it on 24/7 or just occasionally as per your old post?

No, not internal. I use a wall-wart containing a switched-mode power supply. Meanwhile the VFD display is on for 24/7 since 4 years or so in combination with the switching power supply.

I don't know why they die, but they do. I think it's usually the power supply. Whatever the reason, Matt Burkhard did a great job of fixing two of mine. See these threads:
