In need of stabilizer/puck for a Sony SCD-777ES

Perhaps someone who is using theirs as a boat anchor because they can't get the laser parts will either sell or give you one.  Don't lose hope.

Ask Art Dudley.  He thinks that digital developments ended with that player.
Have you tried eBay, or contacting Sony?

The laser in the Sony SCD777ES is notorious for failing. You can find the laser for sale on ebay at around $150 to $300, but some would prefer to just shelve the unit rather than replace the laser. I had mine replaced by a friend in one day. It can’t be that difficult. In any case, there must be one owner of a failed unit that would be willing to part with the puck. I'm hoping that if anyone feels generous, they will respond to you via this thread.
