What CD players have same laser pickup as Nak Drag

What other Nakamichi CD Players employ the same laser pickup as the Nakamichi Dragon CD. I have a Nakamichi Dragon CD player (7 disc music bank system), Nakamichi Dragon DAC, Nakamichi Dragon PS (Power Supply). I need to find a replacement laser pickup and someone to install it.
Hi, Sorry cannot be more specific--but there is a supplier in Ireland
that has huge stock of lasers--I am unable to find the site at this time.

We found him a source of lasers for a discontinued player.

Good Luck
