I would scrap the arm and get something more current. The technology has vastly improved over the last 30 years, especially as relates to the SOTA products. Perhaps they can provide you a refurb arm that they know mates well with their line. It should come with service support.
Need a Magnepan UniTrac I tonearm repaired
I'm the original owner of a Magnepan UniTrac I tonearm that after 30 years of wonderful service in my Sota Sapphire needs rewiring, including the cartridge harness and Amphenol-to-RCA/ground harness. Magnepan doesn't support the arm anymore and my normal service house doesn't want to tackle the job for fear of permanently damaging the arm. Does anyone know of a top-flight operation that has experience working on this rare and special piece?
