Dear chakster, I meant corrosion of the copper wire but assume
that everyone changed those old RCA connectors(grin). I also
stated ''with some exception'' by tonearm producers who made
their own phono-cables. For example Ikeda produced silver cable
which was available as separate and usually bought for the FR-66.
Micro and SAEC also produced or ordered , say, better cables
for their (more expensive) tonearms. But speaking in general
those old Din 5 cables are worthless despite the fact that our
dear chakster thinks otherwise.
