ENTRÉ MC1

[vencel]

I am happy to share my new discovery. I recently purchased some Entré MC1 phono cartridges. Non of them were in woking condition but after opening them up and a little service they are singing wonderfully. I have to admit that I was not expecting such sound from these little gems.
They are way better than the Denon DL-103 family. I tend to listen more and more using this cartridge.
I am not saying that it over performs an Audio Note, Kondo, Kiseki or such cartridges but I am very-very impressed with their sound.

Excellent build.

Finished and ready to play.

Thanx for sharing the pix!
If someone wanted to buy a hollow boron tube with a small line contact laser or drilled thru and bonded with the plate only and no wire,, how much would this cost?
I,m considering trying it on an old Megasonics MC 10 cart that I would use as a base MC rebuild.
Don't know if I could do it, but would like to at least give it a go

Regards
David

What kind of damping pads are there? And what compliances? What glues are used to bond everything?
Inquiring minds want to know

I'm happy you like the pics.
I am afraid I did not understand your question...
Regarding boron tube I am not sure if anybody is selling such cantilever. Boron is usually solid. I've seen a patent about making boron tube but it is very complicated so I am not sure if anybody would make that and how much would it cost.
Solid boron cantilevers are normally not drilled thru like aluminium ones but the stylus is glued to it.
What do you mean by plate only and no wire?

Best regards,
László

Sorry, but this is something that nobody would tell you.
Regarding glue, different services use different glue and I am sure that every manufacturer has his preferred glue.

I have a few MCs with hollow boron tubes, Audioquest 404i highoutput, and recently a Monster Cable Sigma 2000 with hollow boron tube and a coating of some kind overlayed.
Quite easy to see under my scope and reading the literature specs

The plate mentioned is where the wire is wound around.

I don't like the idea of gluing a diamond directly, and would prefer a press fit and glue. I have no evidence as to why I don't like a glued on needle or if it matters at all, but it seems with the forces transmitted, this should be as rigid as humanly possible.
I can appreciate those can rebuild them however any way they can without my nitpicking

 

[vencel]

OK, now I understood. You are talking about the coil former (plate) - cantilever assembly.
I tried to explain that boron tubes are not that common and I don't know where you could buy them.
Monster Cable | Cartridge Data | Vinyl Engine

Sorry, but I don't know where you could buy coil formers with glued-in cantilever.
Perhaps from cartridge manufacturers but I am not sure if they would sell you any.
Despite of this I encourage you to try and contact them.

Was this a complete replacement of the entire canteliver + coils, or a rewind on the existing parts?

I seem to note finer wire and a greater number of turns in the final version? Probably that gives more output?

No, this particular unit did not need recoiling. Actually the factory coils are not the nicest, I am making nicer ones but these were built many-many years ago.
All parts are original.

So what was broken?

So what was broken?

This particular unit needed a good clean, resoldering the wires and alignment of the coil and suspension.

 

[AVWERK]

Can you explain what you did to align the cantilever? No matter what cartridge you look at, it seems the majority have either azimuth errors (difficult for many tonearm mfgs.) or more commonly, slightly skewed cantilever assembles (relative to the cartridge body) and easily compensated for by end user.
You must cut the "rubber" or silicone substance to do this and superglue right?
I say silicone only because I have had 20 year old MC,s that have not collapsed at all or shown anything you expect to occur under the sun.

Which solder was used for resoldering of such a thin wire?
