Lexicon MC-1; DC-1 Power supplies

Has anyone else had a power supply die in their Lexicon MC-1, or DC-1 or 2?

It's happened to me twice now. They use what appears to me to be a pretty cheap switching power supply. Lexicon won't service these units for less than $600 (though for that they do a complete refurb). I had my DC-1 repaired a couple of years ago by local reputable shop and it cost $200.

I love the units for home theater. They sound great and are very user friendly for setup and control, but wonder about the reliability.

Am I just unlucky?

After a power outage, my DC-1 won't start up. I'll check the fuse before pulling the PS. Can someone verify if the MC-1 PS is the same for the DC-1 as found here? http://www.mouser.com/Search/ProductDetail.aspx?R=NFS40-7610Jvirtualkey54020000virtualkey826-NFS40-7610J

In searching a little more, I found that the NFS40-7910 (NFS40-7910J) may be the proper replacement PS for the DC-1. Pretty cheap at $19.99 on eBay -

Can someone confirm that this is the correct PS for the DC-1?

UPDATE. Just received a NFS40-7910 from eBay seller. Couldn't wait to install and test. My DC-1 started right up into diagnostics and seems to be working great again. For $19.99, can't beat it.

My MC-1 also just stopped working - wasn't aware that I should not be subjecting it to cold starts - now I hear a clicking noise when I turn the toggle switch on the back - would it be the power supply or something else entirely? Also, if it is the power supply, does the MC-1 used the same PS as a DC-1? If not, I would really appreciate it if someone could point me in the right direction.

Thanks.

So glad I found this thread, my DC-1 has been acting up for months, after a few reboots and diagnostic tests it would finally start up. Last week it was in an endless reboot/diagnostic test loop. Ordered and installed the power supply from Mouser and everything is back to normal. Thanks again.
