[QUOTE="AudioEars, post: 1100630, member: 14978"] The glue has dried up and becomes brittle hence the change in colour (Light brown to almost chocolate brown) This glue is used to stop the electrolytic capacitors solder joints from coming loose in transport The caps "look" okay but when you have removed the units easy to check on your meter and also give them a shake The dielectric may have evaporated and the foil internals will have dried up thus creating a rattle when shaken Let me know how you get on Regards Audio Ears [/QUOTE]
