3T77A manual and mildew issue


Does anyone know where I can download a copy of a 3T77A (not 3T77) manual?

Also, any idea as to what could cause this kind of mold/mildew on only the axial electrolytic caps, and no other components? Storage humidity? The other components all look like new except for that weird white speckling on every one of the caps (and the deteriorated paper jacket on the large cap)...

I tried to include a pic but got an error that the group does not accept attachments.
