Newbie Advice - New Amp Setup

Hello,

I have been listening to MP3s through a giant old Nikko NR-815 for a few years, but I have dug out all of my records and picked up a Nikko turntable as well. Sound was really great for a few days, and then the right channel started rumbling and cracking, but only in the phono section.

So, now I need to get something. Unfortunately, my financial priorities must be elsewhere right now, and audio must be done on the cheap. Here are the options I am considering:

1. Buy another 1970s receiver/amp. There a couple of Sansuis in my area for around $80-$150

2. Buy a cheap phono preamp like a TCC and continue to use the Nikko, since the AUX section sounds great. If it goes, buy a budget power amp at that point.

3. Go into moderate temporary debt and buy something like the Marantz PM 5004 for $450. (this is not an option I like)

My records are mostly 80s import 12"s and LPs, like the Cure, Pil, Siouxsie, but I also have some nice older Nico, Gainsbourg, etc. as well as new reissues and 180 gram. I would not call myself an audiophile in the techy sense, but I do enjoy good sound.

Any guidance would be greatly appreciated.
