Right now i have one of the rebuilded Technics 205c mk4, Axel did the job more than 4 year ago and it’s still perfect! This rebuilded cartidge belong to my friend and he would like to sell it, because he has two of them and will keep only one. The difference between original and Axel’s rebuilded versions is the structure of the cantilever: new cantilever is shorter and it has a collar, Axel told me it was made by nagaoka and it’s solid rod (not a hollow pipe as the original), elliptical tip is glued (not pressure fitted with hi-end laser techlonogy as on the original). What i have noticed few month ago, when i compared rebuilded version vs. the original version, is much better bass response on the original technics 205c mk4. The highs on Axel’s rebuilded version of 205c mk4 are amazing and even better than on my rebuilded 100c mk3.
I’m pretty sure he can rebuild your Technics cartridge if you are up to replace the cantilever.
BTW I was so curious about those technics that i have asked Dominic (Northwest Analogue) if he could work on the suspension. In the past Dominic has not been able to resolve this, but he has developed and improved damping material for their own mc cartridges, it might work with the Technics! Dominic can try but there is no guarantee. That’s what they said.
