I would go back and retrace all the steps and make sure the correct components are in their proper postions as well as the proper values. This all has nothing whatsoever to do whether the tone controls are in the circuit or not. The tone controls are within the linestage part of the preamp.
That phono is a as simple a circuit as can be. What is wrong has to be something simple and just being overlooked. But make sure you deal with the caps on the selector switch as well.
If need be, unsolder all the RIAA components and redo everything. As I said before, "it can't be much!"
