A couple of thoughts, take them for what they cost:
I did an image search for "ample power 1021a schematic" which brought up this image:
from this thread:
Free: Ample Power 3 stage VR, Model #: 1021A - Trawler Forum
If you cant figure out the colors maybe someone else here who has a better monitor
than what I am looking at presently can see. I will be home later tonight and can use a monitor
with better color resolution.
Additionally, I do not know the scale of these pictures so I am guessing they are 1/8 watt resistors. Since it has overheated I would suggest replacing them with the next higher wattage, which would be 1/4 watt, unless these are 1/4 watt then go with 1/2 watt.
You'll have to solder it in like this:
but nothing wrong with that and in fact gives them better cooling
You can also try finding out who got the panel, and if they might be able to take a look on the actual board for you.
