Assuming that Philips is no longer able to supply these, I can think of several things you might try. You could contact Marantz (phone # at their web site) and try to find a charger for a RC9200 (it's compatible). You could also contact several vendors (by phone), such as bluedo.com or surfremotecontrol.com and see if they can help. FWIW, I'm not affiliated with either web site, just had excellent service from them in the past.
