Picked up a Shure 55 & 55S that were in a barn for who knows how long. Restoration questions...
Tackling restoring the smaller of the 2 (55s) first. Got the case removed but the spring broke at the screw, planning on replacing at least the 2 out wires along with the spring but want to leave everything else electrical origional. Add in some new audio foam to replace the old fabric...
Should I tackle replacing every wire? Seems to be origional, looks like fabric insulation on all the internals except for the 2 that go down the spring.
Also, at the moment have not removed the fabric to clean the diaphragm. This internal fabric seems to be in decent condition all things considered - but should I need to clean that diaphragm... is it a hard replace that fabric? Or can just layer some audio foam?
Lastly the rubber holders disintegrated. Friend has a 3D printer - want to try to print out replacements but will likely fall back to some air dry clay or similar. Any feasible recommendations?
Many thanks to any/all time and advice given!
