You can use a full-function pre-amp (both phono and line stages) for just a phono pickup. The tape out jacks (which are "fed" by whichever input the pre-amp’s selector knob is turned to) are located before the line stage and volume/gain control in the circuit, but the regular output jacks are at the end of the circuit, so the volume/gain knob can be used. HAS to be, actually.
