I'm parting with my A/D/S P650 6 channel amplifer. It is in good working condition, has a few scuffs on the casing, but other then that, it's in good shape.

Here is the link to the product description:

I would like to get $200 out of it, or best offer..

I do not have the manual, but it is available in PDF format from A/D/S.
