[Jukebox-list] Ami D40 cart question

I just received the above machine for repairs. It has been converted to 45 RPM PLAY utilizing the blue adapters.

Mech gripper was really froze up tight. Worse one ever.

That’s all set now and I was testing the mechanics by manually tripping the pinbank. The tonearm dropped to the record and after a few seconds the cartridge fell out dangling on the tonearm wire.

Upon closer inspection the cartridge was held in the tonearm with a wad of now dried and hardened putty.

What would be the best option for replacement cartridge for this considering it’s been converted?

Thanks Rick
