The Micro Seiki is probably a DIN connector at the tonearm with RCA type at the electronics. Try buying a "stock" modern cable, perhaps from someone who had upgraded to a ultra high end aftermarket cord.
One of todays modern tonearm cables from a high end manufacturer will be light years ahead of your 22 year old original, even if yours were brand new.
Add to that, your RCA jacks and internal copper wiring are probably suffering the effects of oxidation. This could be a nice upgrade for VERY little money, perhaps much less than $100.00.
If you succeed with this and the results encourage you, go for a new set of head shell wires. This is another place where new copper could make a big difference.
