...31st Ave in Phoenix, AZ.? This is/was a company that manufactured digital Karaoke machines. I need to know if they totally went out of business or if they regrouped under a different name. I have one of their machines and need to know if there is anywhere I can buy song "chips" for it. The model # is KH300. If there is anyone out there who knows anything at all about Karaoke, can you tell me if any "chip" would be compatible, or does it have to be made specifically for that machine? Any and all help appreciated. Thanks.
