Let me start by saying my electronics skill level is at a very basic level. I have no formal training and what I do understand is self taught from reading and research. And help from forum members like you!
At this point in my project I am trying to understand some things on a power supply that don't make sense to me yet. Here is the board layout from the service manual:
It appears to me that some of the jumpers and resistors are not really doing anything. They are tied to the same trace circuit? What am I missing here?
Thanks!

I have had to delete my reply, as while some of the links are logical, there are some things here that just aren't.
What I commented on, is that some of the links, are just making the traces thicker. For current carrying reasons

Thanks for the fast response! That was my guess too, only thing that might make sense. These power supplies are out of some nice old Denon mono blocks. I would think they gave this design their best effort. How about the resistors there are a few doing the same thing? They aren't shown in the schematic:
I wouldn't know where to look for them lol
I do find R3 intriguing.
With images so rough and layered looking, I would be surprised if I'm looking at a stack of microfiche's that don't quite belong together. Unless they dive through the board to the other side, they can't really exist.

I know, the images are a lil rough... all that is available online and probably lucky to have this much. I was going to ask about that R003 resistor, if that is what you where referring to as being intriguing. I sorta thought it was bypassing the relay contacts for a control circuit on another board in the amp. In order for the relay coil to energize it would need power from somewhere and this is the only place it could come from.
Appears that R003 acts like a soft start to save the switch contacts and is then shorted out by the relay.
Seems this relay has a control transistor related to a plug marked remote. The back panel has a DC input, which may say remote, and the front a standby light.

I didn't pause for a great length of time on it.

Thanks friendly. It is nice to have the schematic stitched together on a single page, mine is spit up over several.
Like I mentioned in my OP my knowledge of electronics is very basic. Can i ask you what you think the purpose of this R002 resistor is for?
And this cute lil set of diodes and resistor between filter caps:

R002: Bleeder resistor for the big caps.
R001 +diodes might be a 'ground loop breaker.'
