I recently got a hold of a H/K AVR 7000, currently doing a close inspection of components. It uses an array of cap brands: Yec, ELNA and Korea Chemi-Con. There's evident heat effects; metal discoloration, cold/broken solder joints....and some swollen caps:
For certain I'm replacing these units, but interesting the ESR readings are excellent and the capacitance is at spec value.
Never seen such stressed caps that still measure as OK.
