Phono preamp

Ive been looking into making a preamp for my dads jukebox. The current amp setup is very tinny at higher volumes. As it turns there is a special filter for phonographs that is called an riaa filter. Record companies use this filter to help vinyl records last longer and increase fidelity.

This leads me to conclude that it may simly be a matter of capitors in the filter section of the jukebox.
