Audiophase CDT432M Personal CD Player

I got this unit several months ago and have had no end to the problems this thing has caused. If you replace the poorly designed headphones that come with it (that have terrible sound and are about as comfortable as ice picks in your ears) then it has an acceptable audio output. I also wound up buying about six different ac/dc adapters before I found one that would fit it (ironically the cheapest of them that I found at Big Lots) but then I discovered the problem of polarity. Most adapters have the option of switching the polarity on the terminal to match different manufacturers products and these manufacturers normally print this polarity on the product (often either where they print such data as FCC compliances and dc voltage or at the terminal port itself). Audiophase (whoever that is) failed to include this. On top of that labeling error, the dc terminal port cover is marked with DC 6V. The device runs on 3 volts so I have no idea why it asks for 6 volts. I wasn't too worried. I thought that I could just go on-line and check the company's website to resolve these issues but after finding what I think is the manufacturer's site, I find no reference to this product. This parent company's (Venturer) parent company (Alco) also makes no mention of cdt432m. I could overlook many of the products shortcomings if only I was able to get the needed information so that I need not bankrupt myself by buying dozens of batteries unnecessarily. The built in battery charger was one of the things that sold me on this model but its useless if it can't receive power. Now I finally have an adapter that fits it but without knowing if I should set polarity to positive or negative, and whether I should feed it 3 or 6 volts, I run the risk of destroying it (or at least the rechargeable batteries) by experimenting. Save yourself a lot of trouble and buy from another company; one that has support for their products or at least will admit to making them.
