wonderful thread here!
I am not that good in working precisely.
I have only tried to be able to use the parts I have/had lying around.
In the german "HiFi- Forum" I have a thread (had, as there´s nothing happening at the moment) whre I showed some of my "skills".
If you are interested, see this:http://www.hifi-forum.de/viewthread-26-7620-1.html
It starts with simply sticking styli into other cartridges and ends up with...see yourself, it´s a bit crazy, but I had a lot of fun.
Some of the "saved" cartridges sound really nice.
(for example the N75 with Ortofon X3MC needle, or the AT95 with Ortofon ? needle)
At least it is very interestig for me to see, wat can be achieved with simple work.
