Hi - I am the proud new owner of a Fisher Studio Standard Record Player. I grew up listening to records and it is a sad fact of time that I have NO CLUE how to use this machine. I'm going to need step by step instructions ... including... 1. Does that rubber mat stay in place and the record goes on top of it? 2. What does that weight at the end of the arm do? It has value choices of 0, 0.5, 1.0, 1.5, etc. How do I use this? and 3. Can someone really clarify the size of the LP - are the largest records the 45's? (for fully recorded albums, not the singles). HELP!
