When my brother used to mix on our dads historic 1's ( the other turntable wasn't allowed ) he would use the TDK cassette deck to blend and make music. I t was amazing. A 2-channel mixer, with 2 inputs. The 1 turntable, had a dime taped to the needle for balance , and I can recall my bro getting yelled at for leaving the dime there. The purpose, to perfect his scratching technique.
