Fidelity Research FR64fx - dead channel fix


After many years of service, my FR64fx tonearm dropped one channel. 



I started sleuthing by studying the vertical pillar.


By peeling off the tonearm height scale (essentially an aluminum backed sticker), the set screws are exposed.


I loosened the set screws to carefully pull out the 5-pin DIN terminal + horizontal bearing housing from the vertical pillar. The unsoldered wire was instantly visible. 

After soldering the broken connection, I re-assembled in reverse order. I used rubber cement to secure the tonearm height scale back to the groove in the vertical pillar. 


Happy listening!
