I recently finished doing a capkit on this psu and have a couple of questions.
As I was doing the capkit, I noticed these resistors with rust. Should I replace them? And if I do what are they? What value?

And my last question.
Is this potentiometer some type of volume gain?

Did you ever figure out the which resistor to get? I need the same ones for my PSU.
 
Just reading the colors, it looks like:
470 Ohm 5% (r21)
2x 1000 ohm 5% (r17 and whatever is next to it)

I assume they are 1watt resistors.
 
I really need help reading that table above? I got a couple of resistors that I can't make out the colors due to the colors being faded. Also I have looked all over the net for a schematic of my PSU with no luck.

When you get a sec do you mind sharing a photo of R1, & R6 resistors please? I can't see the bad colors on mine and I want to order them.

Okay, so sorry for late reply back.

So, after searching my storage all over i could not find that exact model on my spare. I have checked my cabs and they both have the O1Y psu. I believe the one i had like yours left with the cab i sold a while back.
