It looks like you already have vinyls, and you're about to get the Technics SL-23 turntable. What you need now are: an amplifier (with a phonostage), a pair of speakers, and cables to connect them with. if you want to keep things simple and affordable, you can get a vintage receiver or integrated amp and 2nd hand speakers for that vintage sound.
The 'pier' mentioned is at South Harbor, Manila, near Manila Cathedral or Manila Hotel. You can find many surplus items there. But if you don't choose carefully you may end up with junk. Not guaranteed, but maybe it's better if you can monitor the pdvd marketplace, a lot of good deals there from reputable members. Really no need to spend a lot to enjoy the music. Good luck!
