I have been away for a while and am sorry that I missed this discussion last week. I have a Wild-Herrbrugg M5 microscope, (actually I also have an M3), and use it religiously to check for wear on my stylii. Wild-Herrbrugg has been absorbed into Leica, but is still very much in business and these microscopes, especially the M5 are the cats meow for our purposes. We used one for years to check the condition of stylii for our customers when I worked in retail. McIntosh encouraged their dealers to have an M5. Audio Technica encouraged their dealers to have an M3. These instruments are old fashioned, optical bi-focal microscopes. Too expensive by today's standards I suppose, but I am used to using them and and fortunate to have them. I wish there was a way to share them with you.
Stylus Wear Question
Was wondering if anyone can either recommend a digital microscope, and its uses, or should I just send the cartridge out for a pro inspections /repair. .
