What is the white glue runnung dow the capacitiors?
Some say its' for "heat dissipation". I'm not sure about that. I would think it would insulate the heat (like a blanket), than to dissipate it. To dissipate heat properly, it needs a heat sink made from aluminum or a fan.
If your capacitor is overheating, then something else is wrong. They should not get hot. They do go bad, but they should not get hot. If they get hot, then you have a bigger problem. Capacitors should only get warm - if that. Usually they are cold, during operation, unless they are near a heat source.
I believe it is for heat dissipation. On my circuit board, the white stuff is between two capacitors which are close together -- apparently, in an effort to protect the capacitors from the heat coming from the capacitors. The capacitors which are by themselves have not white putty/paste.
Just epoxy to keep them together. Nothing to with the operation of the set. I've seen several sets made like that, with no idea why they would. Nothing to worry about.
