Warranty

Delta I as well as all Legacy units are now out of Warranty. In the unfortunate event that your unit develops a problem we advise you to follow the procedure below:

  • Make sure the unit has the latest Firmware (if it requires firmware).  Does it solve the issue?
  • Try and find your answer on this website;
  • You can submit a question on-line, call your local Classé Dealer or contact a Classé Service Center directly;
  • Try and find information on any of the on-line Forums.

Repair

  • Should your unit require repair, then you have 2 options (since the unit is Out of Warranty)
    • You can try and find a skilled local repair technician to help you repair the defect. Best is to work with someone who has repaired Classé equipment before (we do not keep a list, you will have to ask around).
    • Contact a Classé Service Center to see if they can help you.
    • Where possible, Classé technicians at one of the 3 global Service Centers will help and accommodate any in-depth technical question a local repair technician may have.

CPM Phono Modules

Phono modules for use in CP-500, CP-700 or CAP-2100, with selectable gain (42dB/64dB) and custom loading for MM and MC cartridges. Dealer installation recommended. Please be prepared to give unit serial number when ordering.

Replacement Shipping Box

A replacement Shipping Box can be ordered with Classé. The box is made out of Coroplast®, which is a strong and waterproof material.  Semi-rigid foam inserts ensure the best possible protection during storage and transport. Please inquire with your local Classé Dealer or contact Classé directly.

*) For shipping Legacy units (made before Delta I series) we recommend using the original box if still intact, and to put this box with at least 2 inches of semi-rigid foam into a new corrugated box.

Parts Availability

  • Classé still has an inventory of parts for Delta I and Legacy Models.
  • A local Dealer or national Distributor can inquire on your behalf if certain parts are available.
