Pioneer CDXP23S is an old model and has been top useful for me to find this Manual. CD Player is still repaired.
;
Inventory (Stock): a rather extensive list of service manuals, which are hard to find, especially 15+ yrs old.
Pricing: very reasonable.
Delivery/Response: Very Prompt delivery of product: Placed order and received download access within 1.5hrs.
Service Manual: a rather complete OEM service manual (15.5MB pdf file size). Scan quality was very good, accept for a few circuit board diagrams that were dark; Zooming, however, clarified the image. Has the required information for servicing the LD Player.

Perfect copy of a necessary document and my Sonic Modulator is repaired!
;
Excellent replacement for original Manual. Worth every cent ! I am totally satisfied!
