We are currently maintaining a system that still utilizes five of the old blue cabinets (QCA74) and all of them use the QSY22 power supplies for message waiting. We are starting to have problems with some of these and we only have one spare.
Does anyone know how to repair these or someone who might have a spare in stock?
Thank you.
