Probably the easiest way would be to use a stereo receiver. You can run the headphone output of your ipod into a tape or cd input. The only thing to deal with will be adapting a stereo 1/8" (3.5mm) headphone type jack to 2 RCA type input jacks. You should be able to get this cord at radio shack. You might also be able to purchase a receiver that has a 1/8" input jack specifically for connecting things like an ipod. A receiver, by definition, has a tuner built into it. The alternative would be a tuner and an 'integrated amplifier' which has power amps to drive speakers as well as a pre-amp and input selection switching.
Wouldn't there be noticeable degradation of the sound, due to impedance mismatch, going from a headphone jack (probably 8-16 ohms per channel) into a tape or CD input (usually 100K or higher)? Unless greig774's iPod has a high-impedance output (which I doubt), the standard solution is an impedance-matching transformer to avoid distortion. Another problem is controlling the signal level with no meter to determine if the iPod is overdriving the input. Both these problems are very likely to result in poor audio quality for greig774.
