some might say no its not a must have box but for me if you are really a serious collector i think it is.
i think i have said it before but there is something about the pc550 that reminds me of a tube amp. maybe its just me but it seems to have that kind of warm vibe to it.
some people seem to like the pc55 more because the speakers are better dampened but honestly the pc550 sounds really great as it is.
the way it rolls off the really really low end bass is very good.
they can be finicky with their sliders and with there dx circuit.
also from what i have learned the belt is hard to replace and i can pretty much promise if it has the original belt in it that will happen.
then the tape deck dont sound to good anymore.
