How do I assess cartridge condition?

Post by The History Man » 19 Oct 2017 07:46

Was just in the loft getting the box for the A2D when I found a boxed in all original packaging MC Ortofon Quintet Blue with the bolts and mini screwdriver etc. This was in the bottom of the old box that my rb300 arm came in. Must have been left there by seller. How can i tell if it's any use?

Is there a way without fitting and trying it?

Also found a little black Linn Karma rattling around with a cover on.

Thanks.

The chief concern is stylus wear, and in this situation it is unknown. There is a thread about stylus wear imaging by Ray Parkhurst however this photographic technique is a little complex. There used to be a stylus microscope by Shure, the SEK2, they change hands on ebay.com occasionally. Microscope examination needs about 100-200x magnification and top lighting carefully arranged to reveal the very small wear facets.

Can determine continuity of a cartridge with a multi-meter. This site tells how:

That is a pretty nice and expensive cartridge!($500). It is a low output moving coil though. I would mount that puppy up ASAP if I were you!(provided you have a step up or MC preamp.)

Not possible.

Keep a simple log of hours played, change at around 500 hours, with clean discs.

I have no idea of the condition, age or hours on these.

Why don't you just install it, play a record and see how it sounds. If you are worried about damaging the record, play one that's not necessarily the most expensive in your collection :D
