About

Hi, I'm Graham. On this channel I will do repairs, restorations and modifications on electronics equipment or anything I feel like working on. Lately I've been featuring a lot of vintage CD players and other audio equipment that I find either in thrift stores or purchase online from eBay. Feel free to get in touch with any questions or feedback, which you can email to [email protected]
