A universal remote should work fine. I used to have a 200 myself. I'm pretty sure they used a Philips transport in that unit, maybe Sony. Either way, just go through the list of choices for companies that make transports in the manual they give you for the remote and you'll get it to work.
Remote For Meridian 200 Transport
Does anyone know where I can find a remote control for a Meridian 200 CD Transport?
