Nutone model 2500 rear panel with replaceable cap

Here the red arrow points to a replacement capacitor that was substituted in for a failed component in capacitor C503.  C503 is a multi part "can" capacitor which contains 2) 500mfd @80 volt, 1) 500mfd@50 volt and 1) 200mfd@50 volt capacitors.

One of the 500mfd capacitors in C503 had failed completely and need to be replaced.  When C503 was checked with an ESR meter, the remaining 3 capacitors measured OK.  Then they were checked with a LCR meter to measure their capacitance and the values were correct.
