Depending on your skills it might be nice to fix it instead, those things are becoming collectables now...But if you want to gut it:Seek a good quality amp, not these cheap and nasty class A ones, opt for class A/B circuit.Seek a good quality battery with a higher voltage than what your compenents need - The ones for RC cars are usually good, small and powerful with 7.2V as a standard.Chargers for them are easy to obtain.Add a circuit so you can charge and use at the same time, for example by utilising a headphone jack and adding seperate circuits for charging and powering the components.If you have to use a step down or step up converter make sure to add a proper filter circuit, in most cases a salvaged toroid core from a power supply and 10.000µF electrolytic capacitor are suffient.Without the filtering you will get certain unwanted noise effects messing with the amp.Last but not least: include a circuit to protect the battery from undervoltage, e.g. when running for a long time and battery goes low it is cut off from the rest.This little list should give you some ideas and search terms to get going.Keep in mind that being portable means being low power, so selecting an amp and speakers for the 16-32 Ohm range is always a good idea.Depending on where you live maybe adding a solar panel is an option too.
