Yesterday I gave it a quick clean in one of those tiny pots of tacky stuff.
It cleaned it up a bit. It has left some stuff on it, but maybe it is time to replace the pot. These pictures are looking down from the top. Will see if I get time to tilt it later.
The last two are taken a few moments apart. There is a buildup of crud around the stylus, but much less on the tip. The glue around the base of the diamond shaft looks like crud, but is just glue.
The aluminium is the shiny wight bit, with accumulated dirt on top.
I think the tip profile was originally elliptical, but the edges have been worn away and are the flat bits you see on the sides.
Would be nice to see the profile of the Koetsu as it has had very few hours of play. Pain in the arse to take it off the arm and set it back up though, so I probably won’t.
If I ever take it off the arm I will, but as I have fucked the cartridge once I am happy just to leave it the fuck alone.
TT has not been moved yet as we have to change the contents insurance for that and some other stuff.
When cleaning up a used cart, I have often used a magic eraser (very carefully) it does a really good job.
Just drop the cart into it in a similar way to using sticky pot of gue stuff. Do this a few times and they clean up really well.
If the stylus is really dirty drop the cart onto the surface of magic eraser and draw the eraser away in the same direction the record would go i.e from back to front of cart. Do this very gently just once and no more than a few mm’s.
One of the more common things is that a small hair gets caught by/in the glue holding the diamond to the cantilever & that then in turn attracts & gathers clag. Repeated cleaning doesn’t solve the problem and it keeps gathering clag until the hair is actually removed. That can often only really be done under a microscope.
