Wire up the PT.
Turn it on but do not let juice go through rectified (standby off type scenario).
Wire your OT to a jack with the ground (black) and your highest impedance tap secondary.
Plug a set of headphones into the jack.
Power up the PT and sit the OT on the chassis. You will hear hum when the OT is parallel to the PT and closer to it. Move and angle the OT to a spot on the chassis where you hear the least amount of noise from the headphones.
Mark the drill/mounting holes, unsolder OT from jack and mount the OT there.
THis gives you the least magnetic field interference and reduces hum from the trannies into the circuit.
