Marshall 4010 Gut Shot - Updated: V1 Cap?

[Splitslim]

Thinking about acquiring this Canadian vertical input 4010 but I noticed some.work on the bias resistor and elsewhere. Can someone help me understand what has been modded and whether or not this is one to get? Thanks in advance!

Without looking at it on my workbench, I would say nothing too serious has been done to it except the Canadian fuse bank mod, to comply with regulations.

These 2 resistors and orange caps seems upgraded (red arrows, bottom of board). Any idea what the resistors are for and if the new orange caps are good?

So I brought the amp home and it sounds great. Looked at the inside closely today and all looks in order, minus the cap on the mid tone pot being removed and a cap across pins 6 and 8 on V1.

I know this is to help with oscillations, but what impact does it have on tone? Is it safe to remove and if so, what should I look for once it's out?
