severe groove damage

[EC3970]

Easily seen, it looks like the vinyl is blistered. Actually the space between two grooves has been knocked away.
It happened to one of my older records and to one I just bought new last month and it's made me upgrade to a rega p3 (on order) to replace the dual 505 and new grado cart.

What caused it? Has anyone seen anything like this before?

It would take severe wear for this to happen. Sometimes there are thin places where one groove could meet another if severe wear was to insue.

I mean, we would have to be talking about something like your setup was very out of wack. I've used (as a kid) ceramic pickups that weighed literally 6-7 ounces and the records have been fine.

You could have record gremlins too. Kah kaah!

I have seen something like that on a sealed audiophile:D LP reissue of Horace Silver's Song For My Father (Capitol/Blue Note). In fact, it looked like somebody touched the vinyl with their fingers while it was still soft (? - don't think that can happen), or something really hot was spilled on the grooves, melting them together.

Heck, you never know! It could also be the ghost of Thomas Edison scraping his claws along the groove and howling "Marry had a little lamb, *********!!! Can you hear me!!"... :)

I have no explanation for this...

I had never seen it before either, and now it shows up on two records. One I bought in the 80's (my boxed Sandy Denny!) and one I bought last month. At first I thought it was a pressing error that I just hadn't notice before, but now I suspect the cart did it. I did carefully adjust everything, and use a test record for anti-skating.

As you can imagine, the audio quality of those lp's have degraded.
