Any amp that has a Phono stage will do a old receiver would do nicely, as for speakers just make sure you get something that won't get blown to bits by your amplifier selection. Take my system for example, my receiver is rated for 50watts per channel, my speakers are rated at 30 watts music power so I have to be a tad careful with the volume knob, don't want to blow my speakers into space! I'm sure your local thrift store like Goodwill has some old gear to get you started if not try craigslist, when all else fails turn to eBay but be warned, on eBay prices get high fast and some sellers don't always take care when shipping items. Nice turntable you got yourself there the successor to my 'table, might wanna grab a new stylus and reset the tracking force, to re set the tracking force lift the tone arm from it's rest clip, turn the counter balance counter clockwise until the arm floats level. This is called static balancing your tonearm, when it's floating nicely move the inner ring with the numbers on it to zero, then twist the whole counter balance clockwise to the desired tracking force 2 - 3g for a Shure M75-EJ which is what I think came with the PL-112D. Good luck and welcome to the wonderful sometimes maddening world of records.
