I checked with one of my vendors who also sale and repairs curtis and all types of controllers. They indicated that they did not have a replacement part at this time but could indeed repair the curtis controller that you have. I hope this can help, contact me if you are interested at brad at aerialliftequipment dot com. Hope this helps.

Are you looking for repair or to purchase outright? Flight Systems Industrial Products remanufactures both of these models. We are a Curtis repair center. I can check stock if you are interested in purchasing them outright. Please feel free to contact me [email address removed]
