I have an R300 receiver, haven't used it in a while. Sounds OK, but be careful, they have STK modules in them which could be a little hard to get. Not too fond of the rather cheesy plastic vinyl on the case, looks good from far but far from good.
Tape deck is definitely a K200, a reasonably competent 2 motor logic unit. Got rid of mine some time ago, nice looking but not sounding to my tastes.
