Wurlizter 3500 Parts

Hi everyone,
I'm new to jukeboxes, but I have been collecting records for years. My wife recently bought me a Wurlizter 3500 for my birthday. I've spent some time and work getting it up and running. It's going now, but I need to find two parts to get it working fully. I'm not 100% on the terminology here. First, I need the relay that controls the mute feature. Secondly, I'm going to need to replace the transfer switch soon. It's the switch right by the record carousel. Does anyone know where I can find these parts. Thanks so much.
