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.
