Thank you for that information. I noticed that the German ebay site isn't shipping to the US but ... I did find this on the US ebay site: https://www.ebay.com/itm/DC-1-8-12V-TDA ... SwqMtdsQBH
I'm intrigued by this device. But a question ... where would this connect inside the 1200?
I also unburied an old PC external sound system (2.1 sound) that connects through the headphone jack on the cd-rom. I'll give this a try as well.
