So the upper left should be labeled tube connector/binding post positive input along with woofer positive and tweeter positive?
No, the upper left connection is the input from the tube connection, which feeds the signal to both halves of the crossover circuit.
Upper right is the crossover output to the tweeter.
Bottom center between the large inductor & bottom sonic cap is the output to the woofer. Then the two connections in the lower right are connected to the negative leads of both drivers and then to the negative/return tube connector.
