Hi Tigercat,

Yes,the B- and C+ are connected. The C and B voltages are referenced to common B-. The C battery is used for the grid biasing of the tubes. Grid bias is almost always a negative voltage. If you follow the negative from the C battery you'll find it's connected to control grids of the tubes.
