Hooray!
Thanks to Uwe's excellent video on how to undress a Denon, Amandarae's encouragement and Sir VD's lending me his damaged Denon 103R as a Guinea pig...By George I've got it!
Here is the half-nude Denon clad only in boxer shorts. I have a feeling that nude cartridges have an advantage over enclosed ones in the area of sound coloration (material resonance, cavity resonance,??) but that remains to be heard. The semi-nude cartridge is a necessary compromise for the protection of the fragile signal wires.
The next step is for Sir Remus to retip it then tested/put back into service in Sir VD's gear.
