Hi, Looking for assistance and I am not technical at all. I have a very good but old (80's) Home stero receiver. It works GREAT with the old big speakers but I would like to get rid of the big speakers and attach small new speakers. All of the new speakers that I have looked at have a connection with red and white plug in's. My old receiver only has wires that come out of it that go to the speakers. No plug in options (to old). Can I convert this and use new speakers or am I forced to purchase a new receiver?
