Hello!
I have received a Carver M500 that blows its main AC fuse at power up.
Studying the schematics and looking inside, I notice evidence of previous cap replacement except the solder joints on the two biggest black caps looks original.
Yet, the orientation of one big black cap seems reversed: C509 should have its Neg leg on the Neg trace below--but it doesn't seem so; it appears they both face the same way:

Mind you, the one in question is oddly turned about 30 deg.. not sure if that's usual.
Should I unsolder this cap and turn it?

These two old black caps negative sign is not printed on the surface of the cap, it is not like modern caps marked on the surface, it was marked a black color on the soldering terminal at the bottom of the cap.
If they looks original then they should be correctly seated.
