I am building me a Vibro Champ.

And i need to figure few things out..

I added A and B in the layout with Paint. And i am asking. where does those lines come from.

A = seems to start but ends nowhere..?

B = is propl just 2 lines and one goes in the midlle on the volume pot and the other one to the left right? both going from the 7 on the tube.



Hope you understand what i trying to say:)

Thanks

This is correct, but do you understand what he is telling you ?   Do you know what shielded cable is ?
Shielded cable has a braided "shield" that surrounds the insulation of the center conductor (wire).   That braided wire (the shield) must be pulled back and used as a ground wire.   If you look at a clean copy of your schematic, you will notice that the thin, black line you are asking about is just a ground wire.   It is connected to the input jack and the volume pot ground post.   Follow the lines and you will see that they go to the ground bus.
Good Luck

And thx for the help 

You have to keep in mind that Ceriatione builds clones.   The schematics, for the most part and certainly in the case of a Fender VC, are all in the public domain.    There is no reason anybody should be without a schematic.
Good Luck
