Yes, it was a linear tracking arm. I saw a few on thorens TD125 turntables. I've never known anyone to own one. I had heard that when they were working they were awesome.
Anyone heard of this???
A buddy and I were discussing old turntables, arms and cartridges the other day. He walked over to his closet and pulled out an old linear track tonearm. The brand name.....Radco (spelling?). He claimed that at one time it was the top tonearm, rated by Stereophile as the best arm on the market. It is probably mid 70's vintage. Anyone heard of it. Anyone owned one or heard it.
