Resending because it may not have been seen correctly by all, and the link to eBay is fixed. Thank you John & Peter, When I searched the archives here previously for info West-Tech’s name came up, but most mentions stated that the main guy Gib had retired. I will reach out to them but has anyone had recent work from them? Any thoughts on the “Goldhead”?

They still have a web site. I had them rebuild my Seeburg M100A cartridge and Flock a Turntable platter for an AMI-C It still works but it has been 10 years or so. There was also a Thorpe Cartridge you might check all the Suppliers for needles and Cartridges.

Or a how to video? What about a suitable replacement option, anything available? And, I have seen someone on eBay selling what they are calling a "Goldhead" version M100A cartridge that is supposed to be a better version than the original M100A cart. https://www.ebay.com/itm/125705684214?mkcid=16 <https://www.ebay.com/itm/125705684214?mkcid=16&mkevt=1&mkrid=711-127632-2357> &mkevt=1&mkrid=711-127632-2357 Is that a legit thing? Thanks! Andrew
