hi...Im trying to connect...an american market cassette player (home stereo) which runs on 110V with my european
market sony home stereo amp which is powered by a step down transformer.
of course the connections are for L & R outputs but Im wondering IF it will work fine or -
is there something else that needs attention?
It is very unlikely there will be a problem here. We don't know what your deck is, but the vast majority use DC motors. I did remember that the high end Wollensack cassette decks used an AC synchronous motor to drive the capstan. That deck was widely used in higher end decks from a number of manufacturers in years gone by, but early in the cassette era.
It is possible there are others that use an AC motor, but those decks are the only ones that come to mind. So it depends on the deck, there could be others as well with AC motors.
I am proud of the fact that I could remember the Wollensack capstan motors were AC. I did check to confirm my memory had not failed me.
