Bogen D070 Amp - HELP w/ INFO.

[Wharf_Creek]

I have a Bogen D070 here that belongs to a friend. As I indicate, I'm a rookie at this, and so far have managed to clear up most of my own problems..but I got drafted into helping a friend w/ his Bogus Bogens. So, he sent me the amps AND a Sams photofact on the amp, but the Sams diagram is WAY different from the amps I have in front of me. The Sams diagram shows a single 6U8 as a combination driver / phase inverter. The amps I have here have both a 6CG7 and a 12AX7 in the front end. Also, these amps are LOADED with peripheral parts for use with PA systems. I'm finding it hard to distinguish that which is for the audio section, vs that which is for PA use. So, anyone with ANY info on these amps they're willing to share, I'd be eternally grateful (and so will my friend!). The appropriate schematic would be wonderful....and if there's such a thing as a 'User's Manual', that would be great as well. My name is Tom, and my email address is Wharf_Creek@Hotmail.com. As always, I thank you all for reading the post. Kindly, Tom D.
