Yes. As per our standards in terms of quality and support we offer service and maintenance also for all our discontinued products as long as our supply of spare parts allows it.
Naturally the older a unit is, the more difficult it can get to fix it. But we still even receive the occasional ACD 101 slate for maintenance (it dates back way into the nineties but still has some crazy fans :-) and we won't reject any reasonable service request.
If you are in doubt whether a repair is still viable, contact us via the support contact form or write us at service@ambient.de.
