Just downloaded the Adobe Philips MCD908 Op/Man [48 pages], and there is no mention of what the tubes are, just an explanation of "the golden age of hi-fi", and the more pleasing sound of tubes. However, this is unit is a "Home Theater" set-up [2 channel DVD...but no HDMI output]. Also, it features CLASS D amplification...oh oh! Not that there's anything wrong with a properly executed class-D circuit...but at Best Buy, better grab your your butt-cheeks!
