Beginner questions

Hi all,

I recently acquired a JVC L-L1 in pretty good condition. It's in much worse condition now, because in an attempt to replace the main rubber belt I snapped the tone arm off of the "D" shaped plastic base that its lower section is embedded in. It still moves as intended, albeit a bit slowly because I still need to replace the smaller drive belt which has loosened with age.

I've got two questions: Is there a glue that works on the plastic in these machines? Gorilla brand super glue did nothing to keep the two plastic tone arm pieces together.

I don't have anything in my house to actually hook up the turntable to. What do I need? Is there a dirt cheap amp/preamp available with the proper RCA inputs? I don't want to spend a lot of money on this until I'm sure I haven't damaged the internals with all my fiddling.
