dead cartridge? Darn the Luck ! ! !

I had a new Ortofon Winfield that was internally wired wrong.....they readily exchanged it, ....stuff happens

this is way too old for warranty and it worked fine when last I used it ..... 20 year ago.
I’ve tried every which way to flip phase. Nothing changes it. But I’m not sure which way the head shell is configured. I just assumed logically, left and right, but perhaps it’s crossed like the Ortofon.https://farm5.staticflickr.com/4861/30936942687_5989ca5d33.jpg
Kind of thinking now that lack of use, aging, whatever has messed it up inside.
Don’t think I’m dropping $50 for a test record. This is not my old 24 track Ampex 1200.
I tested another source thru the pre, the pre is fine.
it’s either me crossing wires or the cart failed with age.
From Ortofon tech supp:
"There are two possible reasons for channel missing or level differences:  the incorrect position (rotation - in front view) of your cartridge in the tone arm. The other is a defect in the cartridge itself caused by aging, rotation of the armature or shunt(s) between the turns of one coil. "

You can get the Shure TTR-110 test record on Ebay for about 10 bucks. It will have all the tests you need to check out your cartridge!

I can’t find a wire diagram for my Philips AF 887 tt headshell. So I’m just guessing.

Your Philips head shell will likely be wired left side pins and right side pins, each top-bottom pair comprising a channel.


On the Ortofon OM series, the top two pins are one channel and the bottom two pins are the other channel.

Red is still right channel positive and white is still left channel positive.

green is right channel negative and blue is left channel negative.

@teo - as I thought.  I'll re-set to normal today and try try the phase flip again.  But I think the cart has just aged into an issue.I'll look for Shure.  Good idea.
