Rupert Neve Designs 5014 Failed Cap in The power filter
I am big fan of Rupert Neves stuff, and the Portico Series 5014 widener did not disappoint. Great attention to detail in this box!
The unit had a bad cap in the switchmode power supply filter.
It looks like an impact failure, but hard to say. I changed with the same value with a slightly higher voltage, and the unit seems to work.
The unit is back again...not good. After some time the unit started to exhibit the same behaviour...all lights would click out and on again...Audio pop in the outputs...of course seemly randomly after the unit warmed up for a long time. I put a meter on the +/-18VDC rails and managed to catch an event...but I did not see the power supply dip or spike...
Next I removed the V7-1218D12 DC to DC switch mode power brick (cool device 9-18VDC in and puts out +18VDC and -18VDC at 333mA). I plugged my bench supply into the COM,+18,and -18VDC testpoint and powered the unit. No issues...I am letting it run in for awhile. The Unit seems to draw 225mA on each voltage rail..
