The original power supply is an Advanced Power Solutions model # APS37VI-42.
+5, +12, -12, and +24 VDC
Ebay and Google search results come back with a couple - but they are about $100 refurbished.

Is there no known off the shelf replacement for the original APS supply?  I believe that he told me it is 5 / 12 / 24vdc outputs.  A lot of those switching supplies are pretty similar but the 24vdc for the LNB is a bit weird in todays voltage lineup...

Don’t order one from Ebay with a network logo on it.   I heard those can’t be used to receive CRC, but it may have a good power supply in it if that is all you want.

I just had him specifically check the PS outputs and they all rhythmicaly pulse in time with the relay chattering and display backlight pulsing.  Unplugged, the PS output seems to still be pulsing but not as noticeably.
