The DOL feature without the appropriate (studio) headphones is quite overpowering. With the older, inefficient, headphones I guess this is quite a killer feature.
In documentation like the service manual, the model number is not preceded by WM.
For the rest, it is a plain DDII with a DOL daughterboard with only discrete components.
The prices have been withholding me from trying to purchase one. However, it would only be to complete the ‘gap’ in the line up. Which shows another gap, the DD9.

 

Here's a video I shot years ago that I forgot that I uploaded. About John Edward and this model

 

That is some history there! Browsing eBay on a Windows XP machine. Thanks for sharing.
