i am very new to vinyl and i was just given a technics sl-bd10 and i need speakers but i don't know if that is the only thing i need
Yes, a pre-amp is neccesary; turntables output a phono level which is much lower than a line level, its so low that you cant simply turn the volume up to hear anything. My pre-amp cost me $100 (Art USB Phono Plus) but it can be found for less nowadays. If you don't have speakers and you don't have an amp look on craigslist for any amp that has a phono stage built in (it will say phono on one of the inputs) these will range in price between $50-$300 depending on the brand and the condition. Also check pawnshops, thrift stores and value village for some cheap goldies. If budget is an issue chances are you will not be able to worry about which brand you get, but Sony, Technics, Panasonic, Sanyo and JVC are probably going to be most common for less than $125. Vinyl is NOT A CHEAP HOBBY. You will want to upgrade after awhile to get the best possible sound.
Do you have a Cartridge?
