Can anyone provide Denon DP service manuals?

I am restoring a couple Denon's right now and would find a service manual to be extraordinarily helpful.

Does anyone have these or know where they can be obtained?
Go to Vinyl Engine. That's where I got one for the Denon DP80.
Dittos on that. I had to sign up to their forums to get access to their archives, no big deal, and they have alot of data on older TT's I got some data on my Denon that is more than the owners manual has. I guess it was the service manual. Still don't fully understand Q damping though!
