Pls help me understand this resistor placement on this schematic

[soma89]

So, I am doing some light work on this Lab Series L5 and found that a 10 ohm ohm resistor was removed from its place on the power board - there is a big burn mark on the board where it was.
The 10 ohm resistor was then soldered to "+" side of C208 and then directly to "+" side of C210. Its off the board and just soldered straight to the capacitor legs.

Does this make logical sense? I have a feeling that this would modify the circuit and not be correct.

I'm thinking about just replacing the resistor back to the original spot as there is no damage to the traces or anything. Its just seems like it was a quicker way of replacing the cap as it is a pain to get under the board.

Attached is a schematic of the Lab Series L5 with my indications on it. The resistor circled in red is what was missing and moved to where the blue indicates.

any help would be appreciated thanks!

The plus side of C210 is chassis ground. The plus side of C208 is not supposed to be, so it's not wired according to the schematic. It might work, but it's not schematically correct. I would put it back to factory correct configuration. I also see what looks to be a dodgy cap connection (circled below). I would investigate that, too.

Thank you! Yes that cap is actually going to be replaced. You can see the old 10 ohm there

Here is what it looks like on the pcb

I can't get the picture to open larger? And, I'm old and blind.

hopefully one of these work. The actual resistor snapped off when i unscrewed the cap so i payed it back in place to give the basic idea

So one end of the 10R is connected to the + end of C208, and the other end is going to a grounding screw that must be going to chassis.
As The Dude mentioned above, that is not the proper ground scheme, even though they are all ending up at 'ground'. There are 2 distinct ground symbols on the schematic, and the 10R is not supposed to be going direct to chassis like that. Possibly to deal with ground loops and hum issues.
