[Jukebox-list] Seeburg cartridge holder

Hi all, For later stereo Seeburg cartridge with the yellow / green / purple shoe type styli, I am sure a few years back someone was selling the replacement holder assembly – the clip part where the cartridge pins sit in the tonearm, and the flat locator clips in the tonearm. I need to replace the one I have. I’m pretty certain it was Ron Rich that mentioned the new replacement part a good few years back. The older ones can get loose and troublesome even with the pin sleeves tight. Does anyone know it ? Thanks Nigel, UK
