Hi All, I've heard much talk in this group about the power supplies on the Z3805. After about 10 days with no power here on Long Island (thanks Sandy.), I finally fired up my Z3805. It started producing a real bad smell after a few hours, the classic burnt transformer type. This is my second Z3805 and it didn't smell the first time ran it, nor did my first one smell. I opened the unit and found the 25W 5V, +/-15V (made by AT&T) was real, real hot.
Eventually the smell went away and the supply cooled down a bit. The unit reports all OK, is tracking SATs, and running properly. IMHO It seems this supply was not properly derated for start-up conditions. Is this the supply driving the heater inside the 10811? Has anybody installed a CPU heatsink/fan combination to help in thermal management? Any insight would be appreciated.
