Identifying optical pickups/ laser units

kora · 1st June 2005, 07:44 PM

Can anyone direct me to a list of CD players by manufacturer and model that details the transport used?

I could give you a list (by email) of the lasers in the repairs that have passed by me over time...only a few brands though.
Normally you will find the laser madel number (a sticker) inside the unit when repairing it. Why would you need this list?

I have two CD players (Marantz CD4000 and Arcam alpha 8) with dodgy reading/playing behaviour, and the logical step is to replace the optical pick-up, which on these budget machines isn't cost-effective unless you do it yourself. The part number isn't at all obvious, on these units anyway, although thanks to the kind help of forum members like yourself I was able to identify them.

Also, knowing which units are obsolete is useful when considering buying a used player, which is probably too late if my Arcam CD23 decides to go the same way. Any insight into that one?
