In Reply to: What factors degrade electrolytic filter caps? posted by DaveD on May 8, 2007 at 13:42:04:
Power supply caps as Used in the Haflers (which actually use decent quality components) are long lived. Age is THE big factor in deterioration, as is long periods (years)of non use
IF paranoid visually inspect them for obvious leakage no subtlety there Leaky large PS caps make a mess. When the caps ae old and tired they often need to 'reform' when first turned on after periods of non use (actual length of non use varies with the condition of the caps).
This 'reforming' process is usually evidenced as a Motorboat sound.. Unpleasant and disturbing.. but usually short lived.
Also of note, is that any passably skilled Tech can check the PS caps for ringing.. as a precise indicator of their condition. Doesn't have to be magic.. there is lotsa science available :-)
Personally I wouldn't seriously worry about replacing those caps unless they motorboat at every or possibly every few turn ons.
