Default Schematic for Bogen DB130 ?

Hello Everyone.

I have recently aquired a Bogen DB130 integrated amp that will be needing some work. It is original except for one cap that has been replaced.
I ordered a Sams E-fact (first mistake because I cannot return) for the Bogen DB130 and found several issues/differences between the schematic and top views that I received and the amp itself.
The schematic shows a single 5U4GB rectifier and I have dual 5Y3GT's. There are some can type caps that are not even shown.There is a voltage regulation pot that is not shown and that I have not yet found in the schematic but did find in the parts list.

The amp in question looks exactly like the one HERE .

If anybody can point me in the right direction for a correct schematic and/or parts list for this amp, it would be greatly appreciated. I would even be willing to trade the single rectifier schematic (for a dual) if anyone wound up with the wrong schematic as I did.
I have recently started tinkering with the tube amps and was able to bring a HK A224 with a dead channel back to life with an appropriate schematic. I just don't quite have enough knowledge yet to run without a schematic. I am in the process of reading the 3rd Edition Morgan Jones book "Valve Amplifiers" but don't have the confidence to "wing it" yet.
I would also be interested possibly in salvaging this unit if someone can point me to a schematic for an amp that can utilize any or all of the 12AX7's, 12AU7, 6CG7's, 5Y3GT's and 6AV5GT's.

Thanks Much for any help you can provide.

I have a copy of the users manual, looks like the same amp. http://hasafraker/com/gallery/bogen/ I could probably make you a copy. I could maybe take adigital picture and email it to you, we'll see.
